READ THIS BEFORE RUNNING
Running a nitro kit is fun and easy, but to make this a safe
and good experience you must observe a few rules. This
kit is extremely fast, easily over 40MPH, and can seriously
injure someone if you are not careful.
Where to run car?
• Any running area you choose must be dry. Do not run
car near any water or wet dirt.
• Do not run on public streets. It is very easy to have the
car run over or damaged by hitting the curb.
• Do not operate car in tight confined places. The car is
very fast and will easily hit something.
• Do not run near people or animals. The car is very fast
and will too easily hit someone.
• Due noise, you will want to consider the surrounding
area when operating the car.
• Do not operate the car at night. You will not be able to
drive it without hitting something.
• Do not operate the car indoors. Engine exhaust is not
healthy.
Glow Fuel
• Glow fuel is poisonous!
• Glow fuel is flammable!
• Do not leave in fuel bottle with lid off at any time.
• Don use any fuel other than glow fuel in this engine.
First Time Starting the Engine
Caution! When starting engine make sure the following is
observed.
• Oil the air filter FOAM Element! OFNA #10015.. $9.95
• Set engine Master needle to 4 turns (rich setting)
• Do not do this alone, get an experienced friend to help at
first.
• Fill fuel tank, try not to spill fuel. Do not spill fuel on
receiver
• Hold car off the ground, so it will not runaway when first
starts
• Turn on Radio and check the linkage before starting
engine.
• Turn on car receiver battery switch.
• Always have an air filter on the carburetor to keep dirt
out.
Engine Break-in
• See Engine Page.
Emergency Stopping Engine When Running
• Remove air filter and cover carb. intake.
• Squeeze fuel line and hold until engine stops.
• With a rag, cover exhaust outlet.
Storing Car After Running
• Remove fuel from tank and fuel lines
• Turn off radio in car
• Put a few drops of after run in engine to keep it from
rusting.
• Clear oil and dirt from chassis with a degreaser.
Precautions
• This kit is not a toy. Always run car with a second
person as a spotter and pitman.
• Hot Parts - The pipe, manifold, engine and head are very
hot and will cause burns.
• Rotating Parts - Keep hands away from the drive train,
wheels, and engine when engine is running.
• Radio - Check batteries life before running the car. If
radio does not have full control of the car with steering
and/or throttle/brake do not run until corrected. Failure to
correct this will result in possible injury and damage to the
car or property.
• Glow fuel - Do leave the glow fuel unattended with the lid
off. Fuel contains Methanol and Nitro Methane and is
flammable and poisonous.
Store fuel in cool ventilated location. Refer the glow fuel
label for additional precautions.
• Car Fuel tank - Never store fuel in car tank, it will ruin the
engine if left in tank.
IF YOU DO NOT BREAK-IN ENGINE
CORRECTLY, MAINLY AT LOW RPM,
YOU WILL BREAK THE CONNECTING

ASSEMBLY OF THE CLUTCH INTO ENGINE
Notes:
Non-Pull Start Engines...
• Alum. Washer behind the flywheel is not needed when using Force engines or similar types. O.S. Engines will
require washer spacer.
3 x 5mm Screw
• To check!..place the brass corn #10330 (big hole) against the engine bearing, then flywheel. You should be
covering one or two thread of the engine shaft. If this is the case, you do not need an additional washer behind the
flywheel.
3 X 8mm
Washer
You must cut the engine shaft if too long. Count 6 threads in front of the flywheel and mark. This is all you need to
tighten the clutch nut and mount the flywheel.

But, you must find the #10329 brass corn (sml hole) for Flywheel. This special corn fits the smaller thread
diameter of the engine shaft. It will center the flywheel when tightening the clutch nut.
