Joe,
If gas is leaking from the little screened hole in the bottom if the Carb air-inlet tube, it's supposed to do that when the float needle valve fails to seat and the float bowl gets too full (floods). If you need to run the tractor without doing anything further, try this: Just open the tank shut-off valve, briefly, to let some gas into the carb bowl (if needed), then shut the tank valve off untill you get the engine running, then open the tank valve. I've started my SA many times and driven out of the barn, forgetting to open the tank valve. If the needle leak is minor, the tractor will probably run just fine until you shut it off, then may flood and leak again if you fail to close the tank fuel shut-off valve again. It's possible that small bits of rust or trash are causing the float needle not to seat properly. I've never been a fan of "if it don't work exactly right, rip it all apart and rebuid or replace it". I'd rather find the exact cause of the problem and just fix that. If you run it a while, the problem could go away if the needle starts seating. If you rebuild/replace the carb, bits if trash coming from the tank could still have the same effect, all over again. If the needle valve is really bad or the float is stuck against the bowl, then the tractor would run rough, lope, smoke, and the engine would probably die flooded.The third carb brand was Carter, according to my original '51 SA owner's manuel. Caution, more than one type was used of each brand. Good luck...
