i have a traxxas stampede with a .15 engine and i am having trouble starting the engine. I have a working glow plug and it all seems to be in working order. (engine has good compression, fuel is going through the lines, and the engine turns over strong). I believe there is something wrong with the carburertor. Could it just be that i don't have it tuned correct? I have not done much research on this engine so any information is helpful. This truck has been sitting for a few years.
