Re: Problem with my Carter BBD carburetor at start up
ok... not really a solution but -
had same same problem with a Carter BBDd '85... only when cold too. I rebuilt carb, replaced all vacumm hoses, checked bowl vent operation and vapor purge/capture, did the nutter bypass, cleaned the idle tubes, replaced fuel pump and more ???? The float would drop but the valve wouldn't open and let in more fuel so the engine would suck the carb dry. I never figured out why... too cold to work outside.
I ended up with a small wrench kept under hood and would tap lightly the bowl at each cold start - no more problems. This kept it running thru winter and the following warm season (summer) I replaced carb with a YF. Not high performance, but it ran well cold and hot.
