thanks Rick, I do believe the shut of was not tight enough but anyway I learned about keeping the screen clean . the tractor runs so good I hate to fool with it . it is a very simple carb otherwise once you study it . I do need to focus on other things like the front crank shaft seal this winter. thanks again everybody .

The only time your carburetor should drip is when you take the drain plug out. I recommend a rebuild and follow the manual on how to set the float drop. Also I would check the mating surface of the float needle and seat make sure no burrs or debris.

If the carb. Is as it should be, you can leave the fuel valve turned on indefinitely and carb. should not leak fuel while setting. That said, I do keep mine shut off when not in use, even though they don’t leak.

kully560 wrote:the screen was clog , I removed the air filter rubber hose and sprayed carb cleaner into the screen and when the motor runs now I hear a little whistle like air passing through the screen . I do not think it is the float as the carb is original and the tractor has never been mess with .could be maybe I did not have the fuel shut off valve closed tight enough and gas drip out of the choke shaft instead of the screen . but all looks good so far , thanks

Just cause it's original doesn't mean the float is not the issue. Floats sink...could have a pinhole in it and fill with gas

I was going to say something similar. The carb SHOULD not leak just sitting weather the shut off in open or closed. But sometimes things are not 100% as this one is and sounds like needle and or seat is worn or crud on it or junk stuck in there. It needs to be looked at one day, but if it doesn't flood running and runs fine I'd say it would be ok to just keep fuel shut off when not in use untill symptoms start to increase.
