69 F-250 390 auto with an Autolite 2bbl carb. I overhauled the motor last year and put on a factory reconditioned carburetor at the time. The carb never did adjust out quite right but in all fairness I didn't have the time to spend on it either. It was good enough to get by. Today I went back through it a little. I set the dwell and timing, checked for vacuum leaks etc. The motor idles great and does well out of gear but in drive in the lower rpm's it will sputter and hesitate. There was one other issue as well. Before when trying to start the motor when it was warm, if it had set for about 15 minutes it was like starting a flooded motor, consistently. Five or so minutes it was fine but after setting longer it acted as if it were flooded. Today I advanced the timing to about 12° and it smoothed things a bit. Not sure yet if it resolved anything though. I'm thinking the accelerator pump may need to be replaced although I don't recall any backfires or anything that may have blown it. Any suggestions would be much appreciated.
