I bought a Muggy the other day, I tried to get it running, It would idle for a little while and then die and every time I touched the throttle on the transmitter it died instantly. This is starting to get really depressing, I've been working on it for a while now. Now it won't even start. I can't tell wether it's too rich or too lean this is my first nitro car and I don't know how the engine is supposed to sound when it's set right. Please help me!
