The dashpot on my holley 4150C got stuck open yesterday leaving my secondaries wide open! I manually fiddled with the dashpot arm (vertical arm coming out of bottom of dashpot) and they closed. I sprayed carb cleaner on the arm and manually played with the plunger, but it seemed to be okay. I then tried to unscrew the top of the dashpot to take a closer look, but I noticed this rubber gasket type thing moving as I unscrewed . . .so I screwed them back in, tried playing with the plunger again and saw bubbles coming from the gasket (leftover carb cleaner making the bubbles). What's up?
