Is this the first time out since you built the car? If you have sufficient cooling system, the car is too lean or too much timing.

If you drove it last year with no problems, what has changed?

More info..

I just love these guys that come on here - post up a question - we give offer up our assistance and try to help with a vague description of their problem, we ask for more info or something to that affect and then they never reply back, very frustrating.
