Understanding "Rich" and "Lean" Fuel Mixture

Adjusting the carburetor is one of the most critical facets of running a nitro powered R/C vehicle. The fuel mixture is
referred to as being "rich" when there is too much fuel and "lean" when there is not enough fuel for the amount of air
entering the engine. The amount of fuel entering the engine is adjusted with high and low speed threaded needle valves.
The low-speed needle is located in the front of the moving slide. The high-speed needle sticks straight up at the back of
the carburetor. Both feature a slotted head that is used as a reference and receptacle for a flat blade screwdriver for
adjustments. The mixture is made richer by turning the needle counterclockwise and leaner by turning clockwise. An
overly "rich" mixture will yield sluggish acceleration and performance with thick smoke from the exhaust. A "lean" mixture
can cause the engine to hesitate before accelerating or, in some cases, to lose power momentarily after the initial acceleration.
A lean mixture also makes the engine run hotter than desired and does not provide enough lubrication for the
internal engine components, causing premature wear and damage. It is always advisable to run the engine slightly rich
and never lean to avoid overheating and possible damage.

Engine Break-In and Adjustments

Breaking in your new engine is critical for proper performance. Failure to follow the break-in procedures can cause
damage and shortened engine life. During break-in and when running, always use Losi Nitrotane 20% Sport Fuel.
Although the carburetor is preadjusted at the factory, you must be familiar with the following adjustments and
break-in procedure. If you change fuel or run in dramatically different environments (hot/cold, high/low elevation, etc.)
you will probably have to adjust at least the high speed needle to prevent overheating and maintain proper
performance. Never, under any circumstances allow the engine to rev freely with the wheels off the ground.

Break-In Procedure

1.) The first three tanks of fuel should be run with the high and low speed needles noticeably "rich" (see explanation
below). There should be a slight sluggishness and thick smoke when accelerating with the smoke decreasing as the model
gains speed. At speed, there should still be a noticeable trail of smoke from the exhaust pipe. Run the Mega Baja on a flat
surface in an oval pattern. Ease into the throttle as you accelerate on the straight sections, easing off as you approach
turns—letting the model roll through the turn before easing back on the throttle. This will also allow you to get a feel
for the steering response and handling characteristics of the model.

2.) You can also break in the engine by placing the model against a wall or fixed object and allow the engine to idle
through two full tanks of fuel. You may have to lean the low speed mixture (slightly) as noted below.

Engine Tuning

After the engine is broken in, you can tune it for optimum performance. When
tuning, it is critical that you be cautious of overheating as severe damage and
premature wear can occur. You want to make all carburetor adjustments in
"one hour" increments.

1 Hour

2 Hour

Carb Adjustments:

Make all carburetor adjustments
in one-hour increments.
Imagine the slot in the needle is
the hour hand on a clock. Adjust
it as though you were moving
the hour hand from one hour to
the next or previous one.

Low Speed Adjustment

The low speed adjustment affects the idle and slightly off idle performance.
The optimum setting allows the motor to idle for at least 8−10 seconds. The model
should then accelerate with a slight amount of sluggishness and a noticeable
amount of smoke. The simplest way to check this is to make sure the engine has
been warmed up and let the engine idle for 8−10 seconds. If the low speed mix­ture is so far off that the engine won't stay running this long, turn the idle stop
screw clockwise, increasing the idle speed. With the engine at idle, pinch and hold
the fuel line near the carburetor, cutting off the flow of fuel, and listen closely to
the engine rpm (speed). If the low speed needle is set correctly, the engine speed will increase only slightly and then die.
If the engine increases several hundred rpm before stopping, the low speed needle is too rich. Lean the mixture by turning
the needle clockwise one hour and trying again. If the engine speed does not increase but simply dies, the needle is too
lean and needs to be richened up by turning the needle counterclockwise one hour before trying again. After you have
optimized the low speed setting, the engine will probably be idling faster. You will have to adjust the idle stop screw
counterclockwise to slow down the engine idle speed. The engine should accelerate at a constant pace without
hesitating.

High-Speed Needle

As you turn this clockwise (leaner),
less fuel enters the engine.
Turning it counterclockwise
(richer) allows more fuel to enter
the engine.

Idle Speed Screw

As you turn this clockwise, it
increases the carburetor opening
at idle and increases idle speed.
Turning it counterclockwise
decreases the opening and idle
speed.

Low-Speed Needle

As you turn this clockwise (leaner),
less fuel enters the engine.
Turning it counterclockwise
(richer) allows more fuel to enter
the engine.

Hi-Speed Adjustment

After initial acceleration, the engine should pull at a steady rate while maintaining a two-stroke whine and a noticeable
trail of smoke. If the engine labors and is sluggish with heavy smoke, the mixture is too rich and needs to be leaned
by turning the high-speed needle clockwise in one-hour increments until it runs smoothly. If the engine isn't smoking or
starts to die after acceleration, it is too lean and you must richen the mixture by turning the needle counterclockwise. Don't
be confused by the sound of the engine and the actual performance. A leaner mixture will produce an exhaust note with a
higher pitch but this does not necessarily mean improved performance, as the engine is on the verge of overheating and
may incur possible damage. Ideally you want to run the engine so that it is on the slightly rich side of optimum.
This will give you the best combination of speed and engine life. CAUTION: The engine is too lean and overheating if it
accelerates rapidly with a high-pitched scream then seems to labor, stops smoking, or loses speed. This can be caused by the
terrain, atmospheric conditions, or drastic altitude changes. To avoid permanent engine damage, immediately richen the
mixture by turning the high-speed needle counterclockwise at least "two hours" and be prepared for further adjustments
before running any more.

About Glow Plugs

The glow plug is like the ignition system in your automobile. The coiled element in the
center of the plug glows red hot when connected to a 1.5-volt battery (located in the igniter).
This is what ignites the fuel/air mixture when compressed in the cylinder. After the engine fires,
the heat generated by the burning fuel keeps the element hot. Common reasons for the engine
not starting are the 1.5-volt battery being weak or dead, the glow plug being wet with fuel, or the
element burned out. Use a spare glow plug to check the igniter. If the igniter makes the element
glow, remove the plug from the engine to check it in the same manner. A wet glow plug means there is excess fuel in
the engine. To eliminate this, put a rag over the head and turn the engine over a few seconds with your "Spin-Start."
Reinstall the glow plug, making sure you have the brass gasket on it. The engine should now start.

Testing the Temperature

The ideal operating temperature for the engine will vary with the air temperature but in general it should be in the
200°F to 230°F (93.3°C to 110°C) range. A simple way to check the engine temperature is to put a few drops of water
on the top of the head/heat sink. It should take 3−5 seconds for the water to evaporate. If it boils away quickly the
engine is overheating and the high-speed needle needs to be richened (turned counterclockwise) at least "two hours."
If you plan on racing or prolonged high-speed running, there are several inexpensive handheld digital temperature
gauges available, like the LOSA99171, you may want to invest in.

About the Radio

The JR radio installed in the Mega Baja is a professional level system with more than the
usual features you may find useful. Be sure to read through the included radio manual
for complete instructions. The following is a simple guide refers to items that are
commonly used and/or needed to run your model.

1. Power Switch - Turns your transmitter ON and OFF

2. Steering Wheel - Controls the steering of your model

3. Steering Trim Tab - Allows you to fine-tune the neutral
position of the steering

4. Throttle Trigger - Pull back for throttle and push forward for brakes

5. Throttle Trim Tab - Allows you to set the idle/brake of the model

Radio Operation

It is important that you familiarize yourself with the radio system, as this is your direct link to the model.
Never run your model with low receiver or transmitter batteries.
Never leave the power on or the batteries will not last long.
Always fully extend the transmitter antenna before running your model.
Always turn the transmitter ON before turning the model ON.
When finished running, always turn the model OFF before the transmitter.
For best operation, it will be necessary to keep the "trims" adjusted for both the steering and throttle as noted below.
Steering Trim: The model should go straight without turning the steering wheel. If not, tap the trim lever found just
above the steering wheel in the direction needed for the model to go straight. Each tap of the trim button will be accom­panied by an audible tone indicating a change has been made. It may take several taps to get the correct trim setting.
Throttle Trim: The model should idle without the tires rotating when the trigger is at its neutral position. If not, tap the
trim tab located to the left of the steering wheel to reposition the throttle servo and close the carburetor and apply
more brakes. Note that additional braking force is applied when you push the trigger forward.
Synchronizing the Steering Servos: If you remove the steering servos or the
servo savers you will probably have to make some small adjustments to ensure
they are working together at maxium capacity. With the servo savers removed
and the linkaged attached,
Turn on the radio and reset the steering trim to read "0" (which is neutral) on
the radio screen.
Loosen the setscrews securing the linkage slightly and mount the servo
savers so they are timed as close as possible like that seen in the photo.
Use the steering trim on the transmitter to fine-tune the timing of the servo
savers.
Make sure the front tires are pointing forward and lock the steering linkage in place by tightening the setscrews.

Maintenance

In addition to the service needs pointed out in this guide, you should try to maintain your new Mega Baja for proper
performance and to prevent wear. If dirt gets in the moving parts it can seriously hinder the performance of the model.
Use compressed air, a soft paintbrush and/or toothbrush to remove dirt and dust. Avoid using solvents, if possible, as
this can acutally wash the dirt into bearings and areas not accessible without disassembly, causing additional wear. We
suggest you follow these basic guidelines:
Remove as much freestanding dirt and dust as noted above.
Never leave fuel in the tank for more than a couple of hours.
When done running for the day or longer, let the engine run out of fuel. Remove the air cleaner and pour a little
WD40, or quality after-run engine oil into the carburetor and spin the engine over a few seconds.
If needed, clean and re-oil the air cleaner before installing it back on the model.
Inspect the chassis for worn, broken, or binding parts and repair as necessary.

Adjusting the Slipper

The slipper is a key component of the drivetrain that is designed to help absorb sudden or
large impacts that would otherwise stress various drivetrain parts. You should never run
the Mega Baja with the slipper locked (completely tight). The slipper can also be used as a
tuning aid for extremely slick conditions. To adjust the slipper, start by turning the 1/4"
adjustment nut clockwise (tighten) until it gets tight and the spring is compressed.
Do not overtighten as you will strip the nut. Now turn the adjustment nut
counterclockwise (loosen) one full turn. This should be a good overall setting.

2-Speed Adjustment

Although pre-adjusted at the factory, the two-speed can be adjusted to shift at the point that suits
you best. Under normal circumstances, it should shift slightly before the engine reaches maximum
power. The actual distance traveled will vary with the gear ratio and tune of the engine. There are
two adjustment screws (see fig 1) that must be changed evenly for the two-speed to function
correctly. Turning these clockwise will make it shift later and require the engine to rev higher.
Turning them counterclockwise will make it shift earlier and require less engine speed. If you should
get lost adjusting the two-speed, start over at the factory setting by lightly bottoming out the
adjustment screws and then backing them out five full turns. The procedure for adjusting the
two-speed is as follows:
Remove the gear cover.
Turn the spur gears until the adjustment hole is visible in the bell housing between the large
and small spur gears.
Hold the small spur gear and using your thumb; rotate the slipper forward until you can see the
head of one of the adjustment screws.
Use a 5/64 Allen wrench to make your adjustment in 1/2-turn increments. Use the bent leg of the
wrench as your guide.
Turn the slipper forward 1/2 rotation to adjust the other adjustment screw like the first.
(Remember to always adjust BOTH screws the same amount)

Test drive the model to check the new shift point and replace the gear cover if satisfied.

Never run your model without the gear cover, as it is dangerous and gear damage will occur!

Replacing the 2-Speed Gears

Be sure to replace the
one-way bearing in the
same direction as removed.

Use a 3/32” wrench (provided) to remove the retaining screw (turn counterclockwise) while firmly hold­ing the flywheel with a pair of pliers. Remove the screw, washers and clutch bell, being careful not to
lose any shims that may be used. Remove the ball bearings and brush any loose dirt away from the
bearing faces. Put only ONE drop of oil on the inside face (the side facing away from the clutch shoes)
near the inner race of the bearing. Install the bearings into the new clutch bell. Before replacing the
clutch bell, wipe out the inside with motor spray, lacquer thinner, or a similar cleaner (do not use fuel or
oil-based solvents). Replace the clutch bell and secure with the retaining screw in the same manner
used to remove it. Note: do not over-tighten the screw, as it is not necessary.

Replacing the Clutch Bell

Servicing the Differentials

The differentials should be serviced periodically. Be sure to clean and inspect all of the gears and
replace if severely worn. Always use plenty of high-quality grease (like Losi LOSA3066)on all
gears. NOTE: These can also be made into racing type viscous diffs as noted below. Always service
one diff at a time and pay close attention to installing the housing with the "TOP" marking up so it
can be seen looking down on the chassis.

IMPORTANT:

Always reinstall
the thin gasket.

For Viscous Differential

Instead of grease you can use silicone fluid in the differential
for a limited slip feel as desired for racing. Simply fill the diff
up to the top of the gears before replacing the ring gear.
(Be sure to reinstall the gasket). You may have to replace the
O-rings on the outdrives at the same time you change to this type
of differential if the old ones are worn. Popular silicone fluid
for your model is Losi 10,000cs (LOSA5282) and is available
from your local hobby dealer.

Fig 1.

Fig 2.

Fig 3.

Removing the Differentials

Remove the two screws in the bottom at the extreme end of the chassis (fig1)
Remove the four screws in the bulkhead allowing the bumper/skidplates and pin mounts to be removed (fig 2).
Remove the diff retainers and slide the diff out (fig 3). NOTE: On the front end only you will have to remove the lower

front shock attachment screws and swing the shocks up and out of the way. On the rear end you will need to "pop" off the
rear camber links.

Differential Service

Remove the three 5/64" cap head screws and the top of the differential housing, then the diff.
Remove the four 5/64" flat head screws from the ring gear allowing it to be removed.
Inspect the ring and pinion gears for wear; replace if necessary.
Remove the cross shafts, bevel gears, and shims for the carrier.
Clean and inspect all parts; replace as needed.
Check all ball bearings. Clean or replace as necessary.
Remove pins from outdrives. Remove outdrives, regrease and reinstall.
Lube all shafts and gears with LOSA3066 assembly grease and reassemble.
Load cross shafts with gears into the carrier with extra grease. Apply the rubber
gasket to the carrier and reinstall ring gear.
Lube ring and pinion with grease and reassemble diff into diff housing.
Reinstall into chassis with "TOP" on housing facing up.

Page 10

Servicing the Transmission

The Transmission should also be cleaned and serviced periodically. All gears and shafts should be
closely inspected for wear and replaced if necessary. Always use a high quality grease or lubricant
to prevent premature wear and/or failure.

Removing the Transmission

Remove the gear cover.
Remove the throttle linkage from the carburetor and the brake linkage from the servo arm.
Loosen the four motor mount screws (bottom of the chassis) and slide the motor back.
Remove 2-speed spur gears.
Remove the five transmission mounting screws and lift the transmission out.
Remove the outdrive and ten 5/64” cap head screws. Remove the transmission case half.
Regrease the gears and shafts, inspecting each for wear.
Replace any worn or failed gears.
Wipe out the inside of the gear case, removing any debris, old grease and foreign matter.
Check all ball bearings for free movement cleaning or replacing as necessary.
Reinstall gears on the shafts lubing with LOSA3066 Losi Assembly Grease.
Reassemble the transmission lubricating liberally with LOSA3066 or similar high-grade grease.
Make sure the setscrews in the outdrive cups are tightened (a locking compound is highly suggested).
Install the transmission in the chassis; reset the gear mesh by using a small piece of paper between the pinion
and spur gears, applying pressure while retightening the engine. Reconnect all linkages and connections as necessary.

Rebuilding/Refilling the Shocks

Rebuilding/Refilling the Shocks

Step 1.
After removing the shock,
push up on the lower spring
cup and snap it off of the
shaft. Remove the spring.

NOTE: If you only wish to change
or fill the shock fluid, skip to step 6.

Turn the shock upside down
and, using the included shock
tool, remove the black shock
cartridge/shaft assembly from
the shock body by turning it
counterclockwise.

Step 2.

Step3.
Remove the 1/4" nut by turning it
counterclockwise. Remove the
piston and washer. Remove the
old cartridge. Put a drop of shock
oil on the shock shaft before
installing new shock cartridge.

Hold here with needle-nose pliers

Tools Needed

Step 4.
Install washer onto the shock
shaft until it stops. Slide the
shock piston onto the shaft
against the washer. Reinstall
1/4" nut and tighten by
turning it clockwise.

Be sure to
reinstall
washer

Step 5.
If you plan on completely changing
the shock fluid (suggested), dump
out the old fluid from the shock
body before reinstalling the car­tridge/shaft assembly. Pull the shaft
out so that the piston is next to the
cartridge and reinstall the
assembly into the shock body;
tighten in a clockwise direction.

Step 6.
Note: If you are just refilling your
shocks, be sure to use
Losi 30wt silicone
shock fluid (LOSA5224).
Remove the shock cap and the
small button head screw and
washer in the top of it.
Carefully fill the shock body with
fluid to the top. Move the shaft
up and down slowly to remove
bubbles. Top off with oil if needed.

Step 7.
Holding the shock upright, push
the shock shaft in slowly until it
bottoms out. While holding the
shock shaft in this position, replace
the small screw and washer in the
shock top. If fluid leaks around the
threads of the cartridge, it is
probably not tight enough.

Step 8.
Slide the spring over the
shock body against the
shock adjuster nut. Slide
the lower shock cup onto
the shock shaft and snap it
onto the shock end being
sure that it seats on the
mount. Reinstall the shock.
