Rc nitro stalling

[Ginsters]

Hi Guys

First time on here so hi all ;-)

I have a nitro subrau that stalls when hot and doesn't like full throttle when hot!

When I look at the fuel line when it's cut out it has gone back into the tank so don't know if this could be connected?!

When cold she starts fine and runs well until hot!

HELP!!

Cheers

It sounds like your car is running to lean if the motor is to hot the fuel will vaporize before it gets to where it needs to be, you may need to seal your motor or maybe just richen the needles up to get the temp down.

Your tank compression could also be bad.

As mentioned above, the first thing to do is to seal the engine using a sensor-safe high-temp RTV silicon. The next thing to do is to check the O-ring that seals the gas tank by plugging the fuel line that goes to the carb and blowing in the pressure line that comes off of the pipe.

sounds lean. to tune an engine you need to hear the sound out the pipe. if it sounds like its hard and has a crackle sound its lean. if it sounds light and fluffy, lazy, its fat. the trouble is if the exhaust is loud its hard to hear.
