The Stovebolt Site Forums The Shop Area Engine Shop weepy carb-gasket problem, or float level problem?

I just rebuilt my bendix-stromburg WW carburator, and when I started the engine, it started weeping out of the gasket that seals the top of the carb to the bowl. I adjusted the float level to 3/16 like the kit said, but is this too high? it doesnt seem to be flooding out the carb. maybe the top of the carb is warped and isnt sealing? all screws are tight. I made sure there was no dirt on the gasket surface or the carb surface. what can I do to stop this, or does this always happen?

gmcfan: Does not seem to be shutting off completely. Check needle/seat for obstruction. The float level when set correct, should be below the gasket surface. This indicates overfill condition . Check float itself, maybe bent/damaged
or bad and not shutting off. Take back apart to check out. May also be plugged vacuum idle port as this will do the same and cause overfill and/or hard starting. Check gaskets carefully for nicks, burrs on castings. Coat gaskets with chap stick or boot grease before assembly, as this makes better seal. If all checks out check fuel pump pressure. Maybe possible restricted line causing pressure rise to carb. Good Luck.

Think Chevy! :confused: :p :rolleyes:

Float bowl edge could be warped. Lay a small sheet of glass on your workbench, put a full sheet of very fine sandpaper on the glass, (grit side up) turn you float bowl upside down and "sand the edge" Make sure you keep the float bowl flat against the paper and glass. Check your progress very often, just as soon as bright metal shows around the entire edge stop. Sometimes just a few strokes will correct the problem.
