gas pouring out carb??
I have a 1965 Merc 35HP outboard. Engine runs fine but gas has started
flooding out of carb intake as soon as gas line hooked up. Any ideas?? |
Bad needle and seat in the carb.

Any ideas?? That usually indicates a problem with the float and or needle valve. Possibly the float isn't or the needle valve is stuck open or not seating properly He says gas pouring "out" of the carb, and that it runs fine. I would think that a stuck float would be overflowing "into" the throats thus causing tons of black smoke, loading up, chugging, and such. He didn't say "where" on the carb the gas is pouring out from. Side, bottom, top, etc. etc. -- Mike G. Heirloom Woods www.heirloom-woods.net |

The pressure in the line is forcing fuel past the needle valve. May not be enough to flood the engine when running. May also be lower pressure from the fuel pump than the pressure bulb. |
Take the carb off, disassemble it and give it a thorough cleaning,
preferably soak it in carb cleaner. If you don't have access to that use a can of pressurized carb cleaner paying special attention to all the little passageways and holes. Then blow it out with compressed air. Check the float very carefully. Those old mercs use to use hollow metal floats that would develop pinholes and absorb gas making them heavier. If it is one of the hollow ones, replace it. Reassemble using all new gaskets and needle and seat. Be sure to adjust the float according to specs. "tom" wrote in message oups.com...

I'm not typically a stickler for safety, but I'm hear to tell ya that Spray Gumout will F you up big time if you get it in the eye! Back in '86 I was spraying down the carb of this old Buick with a cheesy 6 banger in it, and that **** hit some passage way and shot back in my eye. I had to CRAW on my hands/knees from the driveway to the front porch feeling around for the hose faucet. Man!. (Ps, I still like Gumout - it wasn't their fault) "tom" wrote in message oups.com...

Yeah, and if you use the regular carb cleaner (gallon can size) be even more
careful. It is some potent stuff. .. "Mr Wizzard" wrote in message ... "IBNFSHN" wrote in message news:leMFe.82739$%Z2.63953@lakeread08...
