Another item could be a stuck choke plate in the closed position making an over rich condition.

 

I think the timing may be the issue I timed the car the 4 degrees and whenever I revved the engine, no advance.... The line on the harmonic bale cer did not move at all. So I checked my distributor and saw there was no vacuum advance! it's Mallory performance distributor. What next? Should I just go buy a distr. With vacuum advance??

 

You have either a mechanical advance distributor, or a vacuum advance distributor that someone removed the vacuum can and proceeded to mess it up. You can look inside and see if maybe the weights are stuck. If someone was screwing around with the weights and springs though, it's going to take a little experimenting to get it set right. With that said, a vacuum advance distributor still performs better than a mechanical one, unless your engine is heavily cammed and isn't producing enough vacuum to operate the advance.

 

Might have rusty oivots on the weights. I took the cap off my MSD distributor and was shocked when the relucter was rusted to to crap and one of the srprings was broken from rusting in half. That was just from sitting on the shelf in the garage for 4 years. I would get a spring kit from Mallory and start with the lightest one. This would get all your timing in as early as possable. I think I'm all in by 2800 rpm with the lightest. There should be a diagram on there web site showing what curve each spring will have.

 

I'm pretty sure it's the timing on this with everyone else.

A friend's car a few months ago had a problem with it dieseling. Timing was dead on and everything and it was right after he tuned it and brought it over to my house. He just hadn't set the idle mixture and idle rpm's and it was about 100-200 rpm's higher than it should have been. When I lowered the idle to where it should have been it stopped doing it. Apparently the carb was just laying excess fuel in the plenum and it was slowly being sucked into the cylinders after shut down causing the problem.
