Check The Oil
To check the oil, remove the dipstick from the engine. (See Figures
below) Wipe clear any oil from the dipstick and place it back in
the hole it was removed from. Do NOT twist the dipstick back into
place, doing so will give you a false reading. Push the dipstick down
until the threads on the cap prevent it from going any farther. Pull
the dipstick out and check the oil level. If additional oil is needed,
please refer to the engine owner’s manual for directions on how to
add/change the oil. After checking the oil, be sure to screw the
dipstick back into place.

until it is full. Do NOT overfill the tank, doing so may cause damage
to the kart or increased risk of fire. Do NOT open the fuel cap while
the go-kart engine is running, doing so may cause serious injury. 93
octane fuel is recommended. Be sure that the fuel is clean and fresh.
If the kart will not be used for 30 days or longer, be sure to use a fuel
stabilizer. Do NOT attempt to mix the gas and the oil. This is a four
stroke engine and does NOT require the mixing of gas and oil.
Bolts/Connections
Inspect the connections on the go-kart that involve nuts, bolts, pins,
and other moving components. Be sure that all connections are
secure and that there are no major problems visible with the go-kart.
If bolts need to be tightened, use the proper wrench to tighten.
21
Tires
Check the air pressure in the tires. Inspect the tire for loose bolts,
worn spots, and damage. Do NOT operate the go-kart with any
damaged, worn, or loose components on the tire. If you have any

dipstick in until the threads catch. Do not screw the dipstick back
into the hole, doing so will cause a false oil reading.
27
Replacing The Spark Plug
1. Clean the carbon build-up from around the spark plug to prevent
carbon from falling into the cylinder when the spark plug is
removed.
2. The spark plug is located above the battery housing, directly

California Emissions Warranty
Your Warranty Rights And Obligations
The California Air Resources Board and Tomberlin Product Group (TPG). are pleased to
explain the emission control system warranty on your 2005 small off-road engine.
In California, new small off-road engines must be designed, built and equipped to meet the
State’s stringent anti-smog standards. TPG must warrant the emission control system on
your small off-road engine for the periods of time listed below provided there has been no
abuse, neglect or improper maintenance of your small off-road engine.
Your emission control system may include parts such as the carburetor or fuel-injection
system, the ignition system, and catalytic converter. Also included may be hoses, belts,
connectors and other emission-related assemblies. Where a warrantable condition exists,
TPG will repair your small off-road engine at no cost to you including diagnosis, parts and
labor.
Manufacturer’s Warranty Coverage:
The 1995 and later small off-road engines are warranted for two years. If any emission
related part on your engine is defective, the part will be repaired or replaced by TPG.
Owner’s Warranty Responsibilities:
- As the small off-road engine owner, you are responsible for the performance of the
required maintenance listed in your owner’s manual. TPG recommends that you retain all
receipts covering maintenance on your small off-road engine, but TPG cannot deny warranty
solely for the lack of receipts or for your failure to ensure the performance of all scheduled
maintenance.
- As the small off-road engine owner, you should however be aware that TPG may deny you
warranty coverage if your small off-road engine or a part has failed due to abuse, neglect,
improper maintenance or unapproved modifications.
- You are responsible for presenting your small off-road engine to a TPG distribution center
as soon as a problem exists. The warranty repairs should be completed in a reasonable
amount of time, not to exceed 30 days.

Defects Warranty Requirements for 1995 and Later Small Off-Road Engines.
(a) Applicability. This section applies to 1995 and later small off-road engines. The warranty
period begins on the date the engine or equipment is delivered to an ultimate purchaser.
(b) General Emissions Warranty Coverage. The manufacturer of each small off-road engine
must warrant to the ultimate purchaser and each subsequent purchaser that the engine is:
(1) Designed, built, and equipped so as to conform with all applicable regulations adopted
by the Air Resources Board pursuant to its authority in Chapters 1 and 2, Part 5, Division 26
of the Health and Safety Code; and
(2) Free from defects in materials and workmanship that cause the failure of a warranted part
to be identical in all material respects to the part as described in the engine
manufacturer’s application for certification for a period of two years.
(c) The warranty on emissions-related parts will be interpreted as follows:
31
(1) Any warranted part that is not scheduled for replacement as required maintenance in the
written instructions required by Subsection (d) must be warranted for the warranty period
defined in Subsection (b)(2). If any such part fails during the period of warranty coverage, it
must be repaired or replaced by the engine manufacturer according to Subsection (4) below.
Any such part repaired or replaced under the warranty must be warranted for the remaining
warranty period.
(2) Any warranted part that is scheduled only for regular inspection in the written instructions required by Subsection (d) must be warranted for the warranty period defined in
Subsection (b)(2). A statement in such written instructions to the effect of “repair or replace
as necessary” will not reduce the period of warranty coverage. Any such part repaired or
replaced under warranty must be warranted for the remaining warranty period.
(3) Any warranted part that is scheduled for replacement as required maintenance in the
written instructions required by Subsection (d) must be warranted for the period of time
prior to the first scheduled replacement point for that part. If the part fails prior to the first
scheduled replacement, the part must be repaired or replaced by the engine manufacturer
according to Subsection (4) below. Any such part repaired or replaced under warranty must
be warranted for the remainder of the period prior to the first scheduled replacement point
for the part.
(4) Repair or replacement of any warranted part under the warranty provisions of this article
must be performed at no charge to the owner at a warranty station.
(5) Notwithstanding the provisions of Subsection (4) above, warranty services or repairs
must be provided at all manufacturer distribution centers that are franchised to service the
subject engines.
(6) The owner must not be charged for diagnostic labor that leads to the determination that
a warranted part is in fact defective, provided that such diagnostic work is performed at a
warranty station.
(7) The engine manufacturer is liable for damages to other engine components proximately
caused by a failure under warranty of any warranted part.
(8) Throughout the engine’s warranty period defined in Subsection (b)(2), the engine manufacturer must maintain a supply of warranted parts sufficient to meet the expected demand
for such parts.
(9) Any replacement part may be used in the performance of any warranty maintenance or
repairs and must be provided without charge to the owner. Such use will not reduce the warranty obligations of the engine manufacturer.
(10) Add-on or modified parts that are not exempted by the Air Resources Board may not be
used. The use of any non-exempted add-on or modified parts will be grounds for disallowing
a warranty claim made in accordance with this article. The engine manufacturer will not be
liable under this article to warrant failures of warranted parts caused by the use of a nonexempt add-on or modified part.
(11) The Executive Officer may request and, in such case, the engine manufacturer must
provide, any documents that describe that manufacturer’s warranty procedures or policies.
(d) Each manufacturer must include a copy of the following emission warranty parts list
with each new engine, using those portions of the list applicable to the engine.
(1) Fuel Metering System
(i) Carburetor and internal parts (and/or pressure regulator or fuel injection system).
