Have a mild low compression Olds 350 with reman QJet, vintage 1981, with APT and no computer. Has been on car since 2005, 15,000 miles and always started after one pump of the accelerator (unless set for 5-6 days).
In last couple weeks, with just one or two pumps before cold start, fires, chugs a time or two and dies. Then won't fire unless I put the pedal to the floor. Then finally fires, runs rough for 5-10 seconds and puts out lots of blue/gray smoke. After 10 seconds or so smooths out and runs fine.
Today tried 3 pumps before turning key. Fired, chugged a time or two then finally reached fast idle and smoothed out. Tomorrow will try 4 pumps.
Choke is setting with first pump. But, what is possible cause of hard starting?
