Yep, two fingers over the carb at about 1200 rpm, and I could hear the rpm come up.
I will re-jet the center carb from .045 to .047, and test it again. Hoping running a little richer will mitigate the tendency to overheat at Interstate speeds.
Does anybody have any opinion regarding plug color as a means to judge mixture? What color are the insulators on your great running flathead?
