Mark,

you must have been writing at the same time as me!

Is the fuel leaking from the fuel bowl leaking externally, onto the manifold, or is it apparently leaking internally, into the manifold. An internal leak can result in any number of performance issues, rich OR lean conditions, poor metering, that sort of thing.

I normally set Clevelands to idle at 1200 rpm warm, so that it drops to 1000 rpm when the a/c compressor kicks in.

I believe 1000 rpm was the Ford spec for the 72 to 74 motors, the 70 to 71 motors were spec'd at 800 rpm, but they had smaller carbs & milder cams. This is all from memory. The point is, Cleveland engines like to idle fast.
