Nitro Engine Starting Addendum

The initial starting of any ABC-style engine can be
difficult if not done with care. Please follow these
guidelines to have a successful boating experience:

Step 2

Adjust the throttle trim to allow a 1/8 open throttle
position. Place your index finger over the carburetor and
pull the pull-starter several times until you see fuel enter
the carburetor through the fuel line.

Step 1

It may be necessary to loosen the glowplug a few turns
to lower the compression prior to the first run. Use the
Dynamite® Glowplug wrench (DYN2510) to make this
task easier.

Step 3

Turn on your radio system and attach a fully charged
glow igniter (DYN1925) to the glow plug. Insert the
starting wand into the Tiger Drive and actuate the
starting switch until the engine begins to run. If the
engine does not start, place your index finger over the
carburetor and actuate the starter until you see fuel
enter the carburetor through the fuel line.

Step 4

The carburetor needles are factory set at 2

1

/2 turns. After
break-in, you may adjust the needle settings to increase
speed and runtimes. Lean the hi-speed needle (turn
clockwise) until the engine has a strong high-pitched
whine and a thin bluish/white smoke stream emitting from
the exhaust system.

Caution: Do not over-lean the engine or permanent
damage to the engine will occur.

Step 6

If the engine becomes flooded, it may not turn over due
to this hydro-locked condition. You must remove the
glowplug, invert the boat and operate the starter several
times to evacuate excess fuel in the combustion chamber.
Install the glow plug and attempt to start the engine again
with a slightly leaner high speed needle setting.

If you still have problems starting the engine, see the

™

troubleshooting guide in the Pro Boat

manual.

Step 5: .32M Low End Needle Adjustment

Once the high end needle is set, adjust the low end
needle with the supplied screwdriver (Dynamite .32M
only). Turn the needle adjustment clockwise 1/16 of a
turn at a time and operate the throttle. There should be
no hesitation from idle to high speed. Keep adjusting
the needle in until the engine hesitates, then back off the
adjustment 1/4 of a turn.

After break-in, the engine will reward your patience with
easy starting for many years to come.
