Stalling Issue (Slant Six w/Holley 1920 Carburetor)

Another thing to check is the ignition timing. All too often carburetor issues are not carburetor issues, but timing issues. Where is your initial timing set? With today's crappy's gas, you're going to need more initial timing to help it run better. I have mine at about 12* BTDC and it runs great.

I've seen references to advancing ignition timing, but this is the first time I've read why. Why does crappy gas = advanced timing? Is there an indicator for too much advance besides ping?

I thought too that someone that knows more than me (okay anyone) would have mentioned the exhaust heat flapper by now. No? :poke:
