Had pinging under wot. unhooked vacuum advance and set timing at 15-32. No more ping.
I am now trying out a 600 mechanical secondary holley that I had laying around. Going to get cold soon and this carb has a choke.
First issue I had is the secondary float filled with fuel. Got it replaced and the floats reset.
New issue is the manifold vacuum port now has fuel in the rubber plug
What are some possible causes?
Probably going to have to take the distributor apart and limit the mechanical advance. The idle speed screw is now open too far. (too much transfer slot exposed)
Hoping to get some timing numbers on my lunch break.
-what rpm is the mechanical advance all in
-how much vacuum advance is being added between 16-18"
