Before or during conversion to pointless
Been setting up a bunch of distributors this year for the Chevy stove bolt engines. Couple of thoughts before or during conversion to pointless ignition, be sure to check the play in the distributor shaft and check that he mechanical advance weights are free. Discovered two distributors where the weights were stuck or sticking. A more powerful spark helps mask starting problems but won’t really do much for performance.
Only picked it up because of checking with dwell and tack and the advance and dwell kept changing, every time engine was accelerated and returned to idle it would be 5 or so degrees different high or low.
Checking the timing on the chevys is such fun with the timing mark down behind the starter but checking engine with the engine on test stand made checking it several times much easier.
