Then that is a good clue,,,,,you surely need advance for power,,,,but you don't need it at an idle,,,,,The Load O Matic distributor needs a spark valve in the carb to figure out when the van is in 3rd gear and when it is at idle,,,,,if you hook its vacuum line to a NORMAL carb without a spark valve, it will get confused and start changing the timing all over the place,,,,,,so if you have a Load O Matic distributor and a carb without that spark valve on it, that's what probably is causing your problem,,,,you need a matched set,,,,,and that Petronix just replaces the points,,,, that vacuum problem will still be there,,,, but I think they might make electronic ignition kits that do away with all the advance units and do it electronically,,,,
