Well I guess I'll try bumping my initial timing up to around 16 or so and see how it acts....what about hooking the vac advance to the manifold vacuum port? Wouldn't that bring up the initial timing?

What timing is everything running? I'd like to hear how everyone is running to give me some idea of whats most often used on these trucks.

Does anyone have anything else to suggest for my problems I'm having?
