I just had my 2 bbl rochester carb rebuilt. It ran hella good for about a week or so. It still runs good but at the stops it idles low and shuts off and is somewhat hard to start and will not start on its own I have to hold the pedal down. After it starts up slowly putt putting here and there with a cloud of smoke its ok untill another stop. Ect ect. As I pulled in to a gas station I took the cleaner element off and seen some smoke. Or vapor out of the carb. And a little bit of fuel out on the side..I have no fuel leaks. I also noticed that the exhaust smells more of fuel. If theres a new float I do not know. But for the price I paid to get it rebuilt I would of expected it to be new. Im thinking I need to replace the choke also.


ahhh the joy of owning a classic. But they are fun to drive!

Sounds like a faulty needle and seat, and/or a
saturated float. It is possible that this carb might even have a brass float, which can get a tiny hole or crack and fill with fuel causing an
overfuel condition. Mickey-d
