Fuel only goes to engine when I cover exhaust

that bolt seemed to do the trick. now to find factory settings again on an engine that RB seems to have forgotten about (K12)
They don't even have a manual for it that I have found!

Good deal bro. As long as the engine starts, you should be able to tune it in. Just pay close attention to the temps. If it starts and smokes, you should be just fine. Remember that nitros hate the cold(40 and below).

Is it aftermarket exaust pipe, Cause I know a guy who bought one, and it didn't supply enough pressure to push fuel into the lines
