I have a 1967 Pontiac LeMans with a 326 engine and a Rochester 2GC carb. Th e engine floods because the carb float sticks. The carb has been rebuilt 3 times: once by my Pontiac dealer, and I have replaced the float. The only thing that seems to work is to rap on the fuel filter with the handle of a screw driver. :( Any ideas?

That carb may have a plastic block that fits over the float chamber--it might be binding. If it has a metal float look for shiny places on the float where it has beeen rubbing. Sometimes the needle is missing the small clip to hold it on the float.

Wish I had it on my bench--I could fix it blindfolded.

Have the same car to this day. Back in the late 70's I found the same problem with the plastic float cover. My car, at the time, needle was sticking in the plastic. I used a small drill bit to open the hole very slighty. The pin should move freely in the hole. I think this card also has a rubber washer and rod on top? Make sure it seals the vent off. This work for me.
