I fought the run on problem .I tried to add an electric dashpot .It was in the way and only fit on the wrong carb. What I've found is more initial advance will let you shut the throttle plates a little bit more to achive the same idle setting . The less idle the less runon. I have a Mallory HyFire VI ignition box. It has programable start retart. I have 8° programmed in and normal 650-700-rpm idle at 12° bftdc so It starts with only 4° bftdc below 500 rpm. Works pretty well.Fast Idle for warm up is the fast idle cam on what would have been the choke. I think I have too high a power valve setting .The engine surges at a cruise on the freway in third at 25 mph. I think I need a lower number power valve that will open a little later in the acceleration proscess.
