Fuel leaking out around primary shaft

(1/3) > >>

phk1967:
When I turn off the car  a good amount of gas starts leaking out by the primary shaft area on the passenger side only. I lowered the float level slightly and put in a new needle but problem is still there any suggestions on what it could be?
Thanks

I just want to add it's a 7028268 carb, mechanical fuel pump, and was totally rebuilt recently and other than running a little rich{still being dialed in} it was fine. Must be flooding somewhere but can't seem to pin point it.

Mr.Pontiac:
Is the base plate bushed??? Can you fisically  move the primary shaft at all??? May iask did you reseat the check ball on the body of carb.??

Leaking at the needle or at the gasket under the seat....Cliff

phk1967:
Yes, I can physically move the primary shafts. A new seat was made when it was rebuilt a few years ago and until recently the carb was fine. It was just sent Cliff's to get the fuel well plugs resealed as the primaries were leaking and I suspected that was the cause and I also put on a new seat gasket. Well I put it together, started it up and it's still leaks on both sides of the primary shafts when shut off. About the only thing I didn't do was reseat the checkball again, which I'm about to do next. Thanks for the help.
