Thanks for your wise response. See attached engine photo showing my non-vacuum advance distributor, with Compu-fire electronic unit inside. The engine runs well, but low rpm "off the line" performance seems similar to the stock 1500 '67 bug I had 30 years ago. But I realize that a 2-barrel progressive carb requires a lot of throttle to kick in the 2nd circuit. D.B. Titus
