Force .18 Nitro Engine Information
IMPORTANT - READ THIS BEFORE STARTING YOUR ENGINE!
For your safety - Your engine is not a toy!
• You will be working with highly ammable fuel, so keep it away from exposed ames
or any thing which might ignite it. Read the safety
info on the fuel container.
• Do not use fuels that were not designed for glow plug engines.
• Keep the fuel out of reach of children!
• Deadly carbon monoxide gas will be released, so do not operate the engine in an
enclosed area where exposed ames or sparks can
ignite it, or where it causes you to inhale it for prolonged periods.
• During operation, the engine may be dangerously hot to the touch
• Do not use the engine for purposes other than in model cars designed for them.
• Mount the engine securely.
Before Starting Your Engine
Oiling the lter
The air lter is essential for keeping dirt out of the engine. A foam lter must be
oiled before running the engine. We recommend using Fastrax FAST63 Filter
Oil treatment. Dab the treatment all around the lter, put the lter in a plastic
bag and knead it until the lter is saturated, but not soaked. NEVER RUN
YOUR VEHICLE WITHOUT THE AIR FILTER.
Adjustments
Your engine has come factory set to allow for an easy start and rich running .
DO NOT alter any of the settings until the running in period has been complet-
ed.
Putting fuel in the fuel tank
Squeeze the fuel bottle, put the bottle’s tube into your fuel container, and draw
out some fuel. Lift up the lid on the fuel tank, and slowly squeeze the fuel
bottle until the tank is full. Be careful here. If you overow the tank it might get
on your radio gear or on your brakes and you may create an unsafe driving
situation. Always keep your fuel bottle closed when not in use.
Understanding the engine terms “rich” and “lean”
Your carburettor has screws that regulate how much air and fuel enter the
engine together, the air/fuel mixture. An air/fuel mixture that is too “rich”
means there is too much fuel, and a mixture that is too “lean” means that there
is not enough fuel for the given amount of air. When the mixture is too rich,
performance will be sluggish (one symptom of this, is excessive amounts of
smoke from the exhaust). There is also a potential to foul the glow plug when
the mixture is too rich. When the mixture is too lean, there is not enough fuel
to cool or lubricate the internal engine components, and damage to the engine
and/or glow plug is almost certain.
CAUTION:
If, while you are driving, the engine stalls because of an overheating condition,
severe damage may have already occurred. Overheating is caused by the
following conditions.
• Fuel mixture is set too lean
• Air leak around carb
• Loss of muer pressure (line falls o)
• Excessive nitro content in the fuel
• Incorrect oil content in the fuel
• No air lter
• Poor quality of fuel
• Contaminated fuel
• Excessive loads on the engine (locked drivetrain)
Your engine will be short-lived if any of the above conditions are allowed
to exist for any length of time. During the rst few tanks watch closely for
any signs of overheating. These will include:
• Steam or smoke coming from the engine surfaces
• Cleaning out and then lagging during high-speed acceleration, as if it is
running out of fuel.
• Popping or clattering sound when slowing down.
Idle speed will surge or possibly diminish to the point of stalling.
To Test For Overheating
It’s important to check the head temperature during the operation of the
engine. The best method for checking the head temperature is to use a head
temperature gauge. There are several head temperature gauges available, and
the temperature readings between these dierent brands of gauges vary. Due
to this variance , the temperature readings will range between approximately
185 degrees and 225 degrees. About 185 degrees is the normal for the GO.18.
If you don’t have access to a head temperature gauge, you can use water to
check the head temperature. Place a drop of water on top of the cylinder head.
If it sizzles away immediately, shut down your engine. If it takes approximately
3-5 seconds for the water drop to boil away, then the engine is running within a
normal temperature range.
Start Your Engines
Running-In
The modern model car engine requires relatively little running in, due to the
use of ABC piston and liner assembly. The engine should be run on a rich set-
ting for approximately 6-8 tanks of fuel, with another 6-8 at a slightly less rich
setting. Once this has been completed, the internal engine components should
be properly seated and a normal setting can be used.
A good idea is to use a running in fuel as it is especially designed for breaking
in new engines without damage.
The best methods of checking on the running setting of the engine, is to rst
check the smoke trail coming out of the exhaust with the car is running. A
very rich setting would allow the car to pull away slowly or slugglish with a
momentary hesitation and lots of smoke from a standing start. When the car is
accelerating at full throttle, the engine will never “Clean Out”. When an engine
cleans out, the speed and the rpms will increase suddenly and dramatically,
as if the engine has switched to second gear. Also, the amount of smoke that
comes from the exhaust will decrease. Cleaning Out is a desirable characteris-
tic once the engine is fully broken in.
As the engine reaches normal operating temperature, it will speed up and
performance will increase. This occurs because the fuel mixture
is becoming leaner with the increased temperature. You will need to richen the
fuel mixture so that the engine continues to run as described above.
When the rst tank is almost gone, bring the car in and shut o the engine. Al-
low the engine to cool for 8 to 10 minutes before starting the engine up again.
Add more fuel. Start it back up and run the second tank of fuel. Again allow the
engine to cool before starting it up again.
The key to breaking in your engine is patience. During the break in period ,
your engine may appear to malfunction with problems such as stalling, incon-
sistent performance, and fouling out glow plugs. Don’t give up.
