I just got my motor running. It has a 426 11:1 piston and an HMF slip on. I am running 93 octane pump gas. Well there seems to be alot of carbon coming out of the pipe. And today, every time I would let of the gas it would sputter (not backfire).
Now I think the problem might be not enough octane. But would that cause it or do I have other problems? Should I cut 93 with race gas? Any help would be great.
By the way I am running a 165 main jet with no lid.
