Thanks Norm for helping me out on the difference between the vacuum and mechanical advance. I suspect I may need to take a closer look at the vacuum advance then. I suppose setting initial to 20 degrees certainly wouldn't hurt anything, since that is where Oldsmobile says it should be
. The hesitation is a small, slight one, more noticeable with a very slight and slow accelerator pedal depression say from a stop sign, old man style, from 0 miles per hour to 3 miles per hour. Any other pedal action and the acceleration is smooth without any hesitation. I can overcome the hesitation by "goosing" it. As Joe eluded to, I really should rebuild the carb at some point.
Everyone, thanks for your comments and suggestions, in retrospect I really didn't complete the tune up and should have. I didn't set the timing per Oldsmobile, I didn't check advance, I didn't check for vacuum leaks, etc. I suppose I am getting lazy, and old...........both.
