I have a 78 impala with a 305 and a factory 2 barrel on it. It runs rich and stalls out sometimes on turns and when coming to a stop. I have replaced the carb with a reman'd one but still no change. I am going to exchange the carb for another one because i think this one sucks too. The spark plugs look like it's running rich, same as before. Another odd problem is I can't read the timing with a timing light. It's too far off or at least appears to be. The car runs ok except for the stalling so how could timing be that far off? Compression is 150PSI, vacuum at idle is 14inHg. No vacuum leaks found with a smoke machine. Fuel pressure is somewhere between 7 to 9 PSI.I tried using a fuel pressure regulator to get fuel pressure down some but that didn't change anything. Could it be the distributor?
