Idle way rich

It wants the timing....there is no doubt.

Someone here has some 10* bushings... Wonder who that could be?

You then can get it at 24-26* initial , 34-36* total , then start tuning on the carb

I don't know what distibutor he has so I didn't assume. Yes, I still have some 10 and 14 degree bushings. The18-18 numbers sure sound like an MSD billet with a black bushing.

Put more than one 4779 on a 400+ inch engines without issue.
