What's the static compression ? Have you done a cylinder leakdown test on the motor ? The carb. calibrations and timing may be poor. How much octane are you running ? (pump gas ?
I don't know the CR on the motor, I just had the carb rebuild and 'tuned' from a carb shop. It runs 93 pump gas. From some of the receipts I have, the motor was built about 10-11 years ago, and has had about 3-4k miles put on it since then.
They want $120 an hour at the dyno shop to tune and said it should be under two hours, I think at the end of the season I'll take it up there and see what they can do.
