What To Do If Your Nitro Engine Will Not Start
It is VERY rare that a fault can be traced back to the engine.
Check the following points below before considering the engine to
be faulty.
1. Check the flywheel is not loose. You should not be able to turn
the flywheel without also turning the engine. If the flywheel is
loose you will need to tighten the flywheel bolt. If the flywheel
is loose the engine will usually start but then cut out straight
away.
2. Do the wheels turn when you pull the starter? If so the clutch
shoes have melted and will need replacing - part 30118
or 21027.
3. Has the Glow Plug burned out? Remove the glow plug and check
if it is glowing. Do this by attaching the glow plug to the glow
start directly and the coil in the bottom of the glow plug should
glow bright red in a matter of seconds. Engines will not start if
the glow plug is dim or not glowing at all.
Solution: Replace the battery and/or glow
plug.
4. Is the recoil starter hard to pull ? If the recoil starter is
hard to pull this means that the engine is flooded (there is too
much fuel in the combustion chamber). At this point don't pull the
recoil starter any more - doing so will damage the recoil spring.
or break the pull cord. Any misuse of the recoil starter unit will
void the manufacturers warranty.
Solution : Remove the glow plug from the heat sink head and turn
the car upside down. Now pull the recoil starter a few times to
expell the excess fuel out of the combustion chamber. Replace the
glow plug and start again.
5. Does the car start, but stalls when the glow clip is removed
? If this happens it’s a possibility that the car is idling
too low
Solution: Look down at the carburettor from above. It should be
all but closed, with just a 1 to 2 mm gap to allow the air in. The
idle setting can be changed by turning the idle screw in or out.(The
idle screw is generally located right next to the carburettor barrel)
6. Go to our help page and make sure you have carried out all the
steps to pre-use and starting correctly and carefully.
7. If the engine feels tight when you pull the pull start try undoing
the glow plug just a tiny bit which will release some of the pressure
and then when the engine starts you can tighten it back up.
8. Make sure you have primed the engine with fuel correctly and
enough. It will not start if there is not enough fuel in the engine
and it will not start if there is to much. There is more info on
the how to start a nitro engine section on our web site.
