Hey guys,

I have been chasing an issue with my rc8t4 for a year and it is driving me insane.

I have tried multiple quality engines and pipes, 2 tanks and different fuel lines.

I have no problem tuning in any other chassis

No matter what I do after a couple minutes of running the idle will get unstable high and lean no matter the carb settings. After a couple of seconds it will flame out.

Right now I have been trying to break in an engine in the chassis with super rich setting.

Preheated the engine and started it. Of course its super rich. Does not even have enough power to move. At some point it will just snap to lean. Then there is now chance of tuning it anymore.

It gets worse the longer the car is beeing driven.

Anybody got a clue?
