Thanks for the input guys. DKNGHT, I can't be sure about the gap but I dont think it's that big .050 Next time i change them I'll try it. I'm running a pressure reg and it stays at 6, and the carb was just redone so the valves are new. As far as the timing off the top of my head I think it's in the 4*-6* BTDC range.
I thinks hotroddin is on the right track.Because I've been waiting for the paint job to be done it dosent have alot of miles on it yet. Around the block, exhaust shop/body shop/alignment shop. Not too much time to burn off the carbon, and if that is the price I have to pay to run the at cam then so be it. But what throws me is the vacum readings. The more I think about it I realize duh, if the vac is so high the power valve would never open so it cant be the reason it's running rich. I cant get it to idle under 1000rpm. Sometimes when it's warm it gets close. But then you put a load on it, ie;put it in gear it stalls. So i bump up the idle and it runs fine excpet for the 10hg of vac, which goes up with acceleration. I've checked it at the back of the manifold,the port at the back of the carb and even the small one at the front of the carb. Isn't that one supposed to have the vac increase with rpm for a vac advance dist? Is there any chance the carb could have something crossed up? I've never heard of that though.
