Engine lags and stalls when initially pressing gas-Solution Found?!

If no squirt, the accelerator pump is worn... They wear out easily on the bbd with the leather of the accelerator pump riding on the metal casting... Get a rebuild kit and go through the carb while replacing the accelerator pump... When installing the new accelerator pump, lube the leather first before installing it to help it "wear in" and not tear when installing it...

I am reviving this thread , hope that is ok....?

My son had his accelerator pump on his 2 BBL BBD carb "fold over" on itself about a year ago.....so he replaced it with one from a kit.....its red with a green cup.....

Well, it has once again "folded" on itself so he bought a new kit and replaced it.......worked great at first.....but then while TESTING, the damn cup folded again....this cup is BLACK.

You mention lubing....he didnt...its not torn, but like I said, partially folded/warped back on itself. what kind of lube would you use for that? Seems like the gas would instantly wash out any kind of oil or grease....????

He is in the driveway now, 90 degrees, and frustrated.
HELP!
