SOLVED! 318 2500-3000 rpm idling issue. Don't think its a regular vacuum leak. Swapped 2 intakes, 2 carbs ,and 6 different gaskets still no luck.

So if I pull up the initial timing would I have to limit the distributor weight? How much timing would a stock distributor be adding? I'm probably gonna put some tape on the balancer and see what it's totaling at.
