I hope somebody can help me I'm a rookie in the Nitro world I have a Acme .15 motor I'm using Track's 10% Nitro fuel I think it's called Red Alert.. I have broken in the motor and tuned it to the best I could with the info that came with the motor. It is running around 260 to 280 heat wise I have a number 8 glow plug med to hot.. I have good smoke coming out of the pipe so it's running rich. What can I do to fix this????
