I neglected to mention a very important detail - the leak leaks down the fuel line when the shut-off is closed tight. If I remove the air-cleaner pipe after a night with gas in the tank and the shut-off valve closed, I get what's leaked into the carb pouring out of the air intake port. Do the fixes with the "O" ring (dental floss, packing) just inside the clamp-down nut cure that kind of leak - or does this indicate a problem with the 'male' screw-in-and-out post's not mating sufficiently with the female shut-off valve 'female' seat? If the second instance is the case, how do I fix that?

Thanks again,

Dave

The rubber ring and/or packing are for external leaks right at the stem of the shut off valve. You problem seems to be the valve not shutting off the flow of gasoline to the carburetor. Is this correct? If this is the case, your valve may be internally pitted or damaged, or may have a piece of crud jammed in it. Have you priced a new valve? While it may cost a few bucks to replace it,it's sure better than having fuel leak into the intake all the time.

The needle valve in your carb, should prevent this, but until you get the carb. fixed, you need a funcioning fuel shutoff. Even when you have the carb. tuned up so it doesn't run over, shutting the fuel off at the tank during periods of non-use is sure a good idea.

I fixed my H fuel valve using a rope packing. I think you can get teflon rope type packing yet and am sure that would do an excellent job.

Did your leak leak down the fuel line or out the nut that tightens over the bent-handle you screw in and out? I'm trying to find out if the packing/"O" ring just inside the nut cures the leak to my carburetor.

Thanks,

Dave

Sounds like the needle valve or float may be sticking a little in your carb also. It shouldn't overflow like that. Sometimes some LIGHT! tapping on the side of the carb will free things up.
