So I am at a point right now where I am using only machanical advance. Initial at 14 and total at 24. It’s all in by 2500 or so. If I advance it more I get some pinging. Does it make sense to put in stiffer springs and delay the advance till a higher rpm? Then I may be able to run more initial.
It’s running pretty good now, and I will probably try to add in some vacuum advance and see what happens.
