T-Maxx 4908 Moves Forward at Idle & Too much Unburned Fuel
Hello Everyone,
T-Maxx moves forward at Idle even tough the idle Needle is at very low, counter clockwise. The LSN is richen. The Clutch shoe spring is fine.
There's a lot of Unburned Fuel coming out from the Exhaust Pipe & dirtying the Front & rear portions of the truck [
].
What can I do to stop this? Plz help

Well, I would richen the low speed needle further until it brings the idle back down to where its a bit more normal, esepcially if u have already lowered it using the idle screw. If richening the low speed needle does not bring down the idle, then u may possibly have a air leak somewhere at which point it is time to investigate where the leak is at and "seal" up that area.

Air Leak, ummmmm ya could be, But I dont, know precisely what to look at. Do I have to see the fuel pipes , the Fuel Tank Cover or what? & Ya sometimes I do see the air bubble in the Pipes. Does the Air Leak effects the Idle Speed.
Thanks
Thanks

Yes, having a air leak will definitely affect the idle speed because it will cause the idle to "surge" or "rise". If u see bubbles in the fuel line(s), then its quite possible u have bad fuel line(s). I would replace both fuel lines and then try it out and see what happens...
