Just for discussion purposes, please allow me to disagree somewhat. Please don't throw rocks at me.

"A leaky Rochester is usually caused by the float setting being set too high,"
If the leaks are caused by improper float setting, why do I see so many of them leaking (see previous pictures) ?
Everybody setting them wrong?
Why don't I see a lot of pictures of the Carter YF leaking in the same manner?

"A warped Rochester won't leak gas all over the place. The warped area is above the top of the bowl."
Fuel doesn't always stay level in a bowl. Go around a curve, hit a pot hole or park on the side of a hill.

"The warped Rochester will leak internally resulting in dead spots or over-rich condition by fuel going into places it is not supposed to go."
I agree.

" Gas coming out around the throttle shaft is usually what you will see."
For overfilling the fuel bowl, I agree.
