dial back timing light was an issue with the msd 6al,it was reading 30*at idle (1100rpm),hooked up an old sear roebuck non dial back and it reads 24* at idle, this is with a dead factory stock distributor,put it in gear it idles at 800-850 rpm little shakey touch gas little it smooths up.now the dist i want to use is an mopar performance out of the electronic ignition conversion pkg, when i tried it before the stock one it wouldnt idle at all in gear,it has had the slots shortened,when it was in another motor if it was set at 20*base it was 35*total.springs are whatever mp put in it.what do i do? do i need a heavier spring to delay mechanical advance some so it doesnt come in so early,so when i put it in gear it doesnt drop timing so much?thanks mike
