Carb on Tecumseh engine leaking gas
I purchased a rebuild kit for this carb. I changed the float, the needle and
the needle seat (rubber gasket). I put it back together and it still leaks gas out of the carb, a fast drip. Any thoughts? |

Err, you sure that float is actually doing anything??
Its got to be completely free. Also some bowles have indentations on the bottom. If yours has that make sure the side that would go the deepest would be on the side where the float extends (drops down) the furthest. Tom |

The float does seam to be free, the deep side of the bowl with the dimple is
in the correct possition. I can feel the float move up and down before I remount the carb. wrote in message ups.com... Err, you sure that float is actually doing anything??

I removed the bowl whjile still mounted to the engine, the fload mover fine.
I opened up the gas valve and lifted the float gentley up and and the gas stoped flowing. I did this a few times and the gas stoped flowing every time. I mounted the bowl back on the carb, opened the gas valve and it still leaks out the top on the carb. The float must not moving after the bowl is attached. The bowl is mounted correctly, the deep side away from the hinged part on the float. "SlipKid" wrote in message news:n_Ulf.27274$ih5.11444@dukeread11...

It's possible that the tang on the float bowl assembly may have gotten bent, allowing tthe float to raise too high in the bowl. |

Another possibility that I've run into with these before is that the
float may have a pinhole somewhere. Take it out and shake it gently near your ear. You might hear or feel gasoline sloshing inside, which means you should get a new float (some people might suggest soldering the hole, but I'm not one of them). |

just noticed that you've already changed the float, disregard my
previous post (though it IS possible to have a bad, new float, it's unlikely). I think there's a specific adjustment you need to make per Tecumseh instructions by putting a #4 drill bit (0.210") between the carb body and the free end of the float, make sure the needle bottoms out with the float at this height by "tweaking" the tab on the float just a little up or down as needed. |

And ... the float height (position where it closes the valve) must be
set correctly, or ... the carb floods. This is not rocket-science- just get the specs, meet them, and run it. J |

Where is it leaking from; the throat or around the bowl? Did your rebuild kit include gaskets for the top of the bowl and the bottom retaining nut? If it has one, did you check the tickler drain on the bowl? Did you check the float to be sure it would float (no holes)? Adjust the float level? |

Carb on Tecumseh engine leaking gas
I can use the snowblower, thats the main thing. I just shut off the gas
valve after I use it. I cannot solve the gas overflow problem. I changed the float, needle and the needle seat. There is not much to it, but it has me baffled. Oh Well.

I guess you might want to check the new float for any leaks, it's a
long shot, but it would cause this type of problem. I know you've already changed it, but it's still a possibility that you've had the misfortune of buying a defective or damaged float. |

I know you've already changed it, but it's still a possibility that you've had the misfortune of buying a defective or damaged float. Or, could the float be hanging up on the cup when it's installed? Has the cup got a dent or ding? Could a section of cup seal ring be coming adrift and obstructing the float? Does the cup have a drain valve? Could that be interfering? -- Chris Lewis, Una confibula non set est It's not just anyone who gets a Starship Cruiser class named after them. |

I installed a new bowl gasket, the bowl does not have drain. I don't know
where the float is hanging up. I rechecked the new float, it does not have a hole in it. "Chris Lewis" wrote in message ...

I have the same problem with Tecumseh lawnmower. I wonder if the
little clip on the needle valve could cause it to hang if not turned the correct way? Diagram shows the closed U facing forward and the open end facing towards the rear. The diagram also shows a small O-ring between the bowl and the stem. I'll bet mine came off when I removed the bowl. Oh well, I installed a shut off valve and just turn it off as I head in for the old barn. |

worst case scenario is just keep on searching
on ebay and find one on there for cheap. If you do and it solves your problem for the moment then your in business. Keep the old one as a spare for those sneaky blizzards when all hell breaks loose. |

Hi slip I have a suggestion. There could be rust or dirt in the gas. If
you get rust in the inlet it will flood it. Also a rotten fuel line will leach bits of rubber into the carb causing flooding. It could also be possible you put the neoprene seat in upside down. The side with the little groove all the way around it goes in first. Good luck. |

If it's too high it would turn off. As the float raises, it should close the seat. I'm having the exact same trouble. Remove the bowl and I can get it to operate properly. Install the bowl and it acts like a bad float or needle and seat. Tweaked the tab several times. -- for full context, visit https://www.homeownershub.com/mainte...gas-59950-.htm |

What did you find? I am having the exact same issue. No one can answer. And instead of a carb rebuild kit, I bought a brand new one. New float, needle and seat, etc! I adjusted the float level at least a dozen times by now. Just like you say, it works fine without the bowl attached. Secondly I bought ANOTHER new carb from amazon for $15 thinking I just had bad luck with the previous new one. Guess what, it does the same thing. -- for full context, visit https://www.homeownershub.com/mainte...gas-59950-.htm |

In 45 years I've seen more dirt in needle valves than sunk floats by a LARGE margin - particularky wiyh rubber hoses and ethanol gas. Methanal is VERY rare in motor fuel - even most gasline de-icers no longer use methanol. Of the few sunk floats I've seen, the vast majority are brass floats that have cracked - I've soldered a few over the yeats but I don't think many were tecumsehs. I do remenber a few cork floats that had the shelac stripped off of them by methanol gasline drier WAY back. - and a few fuel guage floats on some Pipers and Aeroncas |
