FUELLING
15
a
a.
Remove the cap from fuel bottle nozzle.
b.
Squeeze the fuel bottle, insert into fuel, and draw fuel into the fuel bottle.
c.
Lift up the lid on the fuel tan and fill car's fuel tank with glow fuel slowly
Be careful. If the tank overflows 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.

Fuel Selection

Choose a fuel from a reputable, brand name company that is approved for car/truck use. Do not use
airplane or boat fuels in your truck. Choose methanol based model engine glow fuel that has a nitro
content in the range 10%-30% and 5% to 18% caster/synthetic oil content for lubrication. Lower nitro
percentages will generally result in a cooler engine running temperature and therefore last longer before
needing a rebuild; cooler-running engines also generally produce less power.
20% nitro is the most widely used fuel in these engines. Fuel color is for identification purpose only and
is not important to performance or durability of your engine.

PREPARING THE ENGINE

16
a
a.
To start an engine, first remove the glow plug.
b.
Prime the carburetor by squeezing the primer bulb while watching the fuel come through the line
and just reach the carburetor inlet. Then, give the bulb another 1/4 squeeze(1/8thinch).
BE CAREFUL NOT TO SQUEEZE TOO MUCH or the engine will become flooded. Attempting to start
a grossly flooded (or hydro-locked) engine (full of fuel) can cause serious damage to internal engine parts.
c.
Check the glow plug by plugging it into the glow plug igniter. The glow plug element should light up
brightly. If it lights up dimly, then the glow plug igniter is low (and it needs recharging). If it does not
light up or the plug element looks distorted, then the glow plug is bad (replace with new one). After
checking, reinstall the glow plug.
The glow plug used for this engine can be: Thunder Tiger 9281, McCoy #9 / #59, Novarossi C4S /
C5S / C6S,OS #8 / #A3 / #A5, and Picco P6S / P7S.
