WD starts but only runs a minute

My 1950 WD is killing me. It fires and starts, but only runs for about a minute. At the minute mark it just sort of putters and stalls.

I think I have it narrowed down to a fuel problem. I recently replaced the carb (the original was shot - I got a replacement Zenith). I had it running fine for a bit - even did some chores. Now it's the symptoms I mentioned. I went back and looked at some other posts about similar problems. I took out the sediment bowl and screen and cleaned them. I took the carb off, cleaned it out with gumout, and blew it out with the compressor. I even tapped it with a hammer in case the float was stuck. I made sure I have good gas flow to the carb - which I do. I noticed that the carb fills with a lot of gas when I turn on the fuel (it actually leaks out a bit at the bottom).

Any suggestions? If my wife rolls her eyes at me one more time when I tell her that I've ALMOST got it figured out, I may jump off a building.

Thanks!

if you got a warranty with carb and theres no rust in bowl you mite see about getting a replacement

Good Luck

It's a 6 volt, positive ground, electric start. the coil is brand new (I recently replaced all the wiring, actually). I was getting good blue spark last time I checked, but I haven't checked that recently. I did notice that the plugs got fouled regularly. Could it be a bad cut-out or something else electrical? Bad rotor? I did not replace the cap and rotor nor any of the ingnition wires, but as I was getting good spark I didn't see the need as they appear to be in good shape.

Are you getting to much gas? It really sounds like not enough though. I would think it is still the needle valve sticking. Are you tapping it right after it stalls? It won't do any goodd to tap it when the bowl is full of fuel.
