ENGINE TROUBLESHOOTING GUIDE
one to see if the problem goes away.
You can view the glow plug
element by removing it and touching it against the engine head
while pressing the EZ-Start button. The glow plug will not light unless
it is grounded against the engine. Glow plugs can be damaged by
particles in the combustion chamber or by running the fuel mixture
excessively lean.
Traxxas makes three glow plugs. The standard hot plug (part #3230)
is the stock replacement plug for Pro.15 engines. The optional super-
duty (part #3232) plugs will last longer in most cases; however, it is a
medium temperature plug so performance may be reduced slightly.
Do not use plugs with idle bars!
Carburetor
Dirt is the main enemy to your carburetor. If you notice a sudden
change in the fuel mixture (lean) and performance of your model,
you may have dirt lodged in the carburetor. To dislodge a dirt particle
in your carburetor, try screwing the high-speed needle all the way in
and then back out to its original settings. If the engine doesn’t return
to normal operation, then try backing the mixture screw out and
priming the engine to force fuel through the carburetor. Return the
mixture screw back to its original setting. The engine will be flooded
at this point, so follow the directions for relieving a flooded engine.
If this fails, then the carburetor will need to be removed and cleaned
with denatured alcohol. Do not blow on carburetor passages or fuel
lines with your mouth. Fuel and solvents are extremely poisonous.
To prevent this from occurring again, insert a fuel filter in the line
between the tank and the carburetor.
Piston stuck at “top dead center” (TDC)
“Top dead center” is the position where the piston is at the very top
of the tapered sleeve. Occasionally, an engine can get “stuck” at this
position. This is most likely to happen on new engines during break-
in, but can also happen at other times. If the engine is stuck at TDC,
use the following procedure to release the piston from the sleeve:
1.
Remove the glow plug using the included tool or 8mm (5/16”) nut
driver, and verify that the piston is at the top of its stroke.
2.
Use a flat blade screwdriver to rotate the flywheel. Place the blade
of the driver into one of the grooves of the flywheel and push
down, turning the flywheel counterclockwise when viewed from
the front. The flywheel should turn, unsticking the piston from the
sleeve.
3.
Put two or three drops of light machine oil into the glow plug
hole to lubricate the piston and sleeve. Do not use too much oil—
it will hydro-lock the engine. Verify the starter will spin the engine
with the glow plug out.
4.
Rotate the flywheel so the piston is at bottom dead center and
replace the glow plug with the gasket. Reconnect the blue glow
plug wire.
5.
You should now be able to start the engine with the EZ-Start.
