carb leaking

I replaced the head gasket, put the tractor back together, did a valve adjustment, and I must have left the choke wide open because when i turned on the gas is started pouring out of the carb between the time i went inside for the battery and came back out. I turned off the gas, and the gas finally stopped dripping but now when i turn the gas on I have a drip from the very bottem of the carb (original M carb im pretty sure) any ideas?
 
I don't think your choke is a factor. Your needle valve is bad or the float is stuck or full of gasoline.
 
Just open up the carb by removing the screws that connect the top to the bowl and you can inspect the float and the needle and seat and see what appears to be the problem. You may need to get a carb rebuild kit with a new gasket and other parts. A carb kit for an M should be $25 or so at TSC or probably cheaper on ebay and such places. It is an easy job to work on, generally.

The choke has absolutely nothing to do with it.

The drip from the bottom of the carb is normal, nothing there to fix.

The needle valve has picked up a tiny speck of rust or other foreign material, might even be a bit of varnish from old fuel. The cure is to give a god, sharp rap to the top front of the carb, just below where the governor tube attaches. Use the handle of a good sized screwdriver. The idea is to jar that needle valve just enough to unstick it.
 
A choke only works when there is a vacuum from the engine, so that is why the choke didn't cause the problem. I agree with everyone else on how to fix it.
