Six Pack Carb Fuel Leak

As far as the EGT go, not sure how much weight should be put in them for idling. Fuel distribution at idle has alot to do with manifold vacuum, engine specifics and intake and exhaust. The fuel droplets are moving toward the lower pressure.

For WOT, distribution can be changed with spivies and notches. The replacement carbs are not the same as the OE carbs. For racing, the tips in the old DC bulletins are probably the place to start.
