Start out NGK 8 heat range.
Watch the ground strap and the cad burn.
Fat: Ground strap only colored:

Closer and probably close enough for you. Taking about 3/4 of the cad.

Thank you very much!!!!!!!!!!!!!!!
If I understand this correct, leaner means hotter and will burn the cad off? also a new set of plugs every pass or does it take a few passes to get coloring in them?

Leaner burns more cad and will probably take a couple runs.

Thanks again.
Alky doesn't detonate like gas, right?

I won't say does not detonate but less prone to. Keep timing conservative at 34 degrees. Whatever you think will be fat.....fatten that 10 more. Get it down the track alive...it will still run good fat. Then lean from there. Wide tuning window.
