Last night as I was out in the garage annoying the neighbors I started playing around with the accelerator pump and just for the heck of it I moved the link to the other holes and tried it. On the top hole it bogged real bad and almost stalled. On the bottom hole it was much better. It was on the middle. I think I am gonna go and put the calibration kit from edelbrock in it for my altitude and see what happens. Along with the advance kit.
I have had that problem too but with my tractor and not a car engine. It is an old farmall super c and it came with firecrator aluminum high compression pistons as a dealer installed option originaly in 1953. The original owner must have replaced the distributer with the wrong one at some time and it was a dog after I rebuilt everything on the motor. I ended up haveing to get the correct distributer shaft and springs for the application from the IH dealer and it cured it. The aluminum pistons required a much different curve then the more common iron pistons. I am betting that is most of my problem too. The mechanical advance will reach 22 deg max at 1200 rpm and with the vac hooked up it will go to 40 by 1650. What do you think I should shoot for. I'll bet the dist came from auto zone. I might end up having to replace the whole thing with an msd or mallory or something.
