Should be a Rochester 4GC.

My 4GC had the same problem - it's from the rubber boot getting too old and maybe exposure to ethanol in gas, etc. You can get a new carb kit at Napa and it should have the rubber plunger piece. Worth saving the rest of the kit and rebuilding the carb as well.

You won't have to remove too many screws to replace the boot itself.

You can view the pages of the manual for that carb here:

thanks for the site and help.. can i just buy the boot... i have a kit for the carb already but its missing that boot... just my luck! what is the part that the boots for called?

fasteddi

is it called the pump plunger boot

Same thing happened to me and I had to buy another kit! The Napa kit had the boot inside and the one from Fusick didn't.

Officially called "Boot - Pump Plunger" here on this page:

What you're playing with is the accellerator pump which adjusts your fuel flow when stepping down on the Noisy pedal or some call it the Gas Pedal
