Rochester carb seeping fuel.

[john3931]

The Rochester 4 bbl is seeping a little fuel out of a hole after acceleration. I am trying to get a good picture of where it is. It is behind the fuel filter housing down toward the bottom of the carb. There is not fitting in the hole and no place where it looks like a hose was disconnected. I noticed it before and after rebuilding the carb.

A little more information. The passage way goes over to the pump discharge ball and retainer. I am thinking that maybe it was plugged. The carb is a 4MV style.

After sifting through the little pieces of debris on top of the intake manifold, I found a small plug that fit in the hole. it looked kind of like a piece of lead shot that was peened in the hole. Even had black paint of it.

Is it still leaking?

Didn't get the plug back in yet. Have to take carb back off to do so.
