Hello Folks:
My 427 S/O is equipped with a turkey pan. This engine is running very rich despite the fact that the timing is by the book. A friend suggested that the turkey pan might create a flow of gas between the 2ndary and primary venturis of the carb creating a rich running engine. Any thoughts on this? I don't think this is correct but hey you never know...Please forgive my lack of FULL knowledge on this topic. I have a 1/2 phenolic spacer and a 770 cfm Holley Carb.
Tks for the input
