Another Timing Question

[rhuebner]

I have my timing at +7 right now is that to much with my setup? And also are my domes the right size? how do you know.

-4mil 68 bore Cheetah Cub

-4mil hot rod crank

-wiesco pistons

-hemi head

-20cc domes

-dual 35mm keihin airstriker carbs on 109 race gas

There will also be Shearer inframe pipes on it.

Thanks for the help.
