Simpicity snowblower leaking gas

I have a simplicity snowblower with a 8 hp tecumseh engine. The carburetor leaks gas out of the choke orifice when running or when off. I rebuilt the carb with new needle and seat. Still the same. The engine runs fine. When I pull off the hose at the carb from the primer bulb the leaking stops immediately. When I drop the bowl and push up on the float the gas also stops. Help!!!!

You may need to adjust the float level. The tang that the needle rests on can be bent to allow more or less fuel into the bowl b4 the supply is shut off by the needle and seat. Also make sure the seat is properly installed. The grooved side of the seat should go down.
Refer to this manual for float level adjustment.

I have done that. What I don't understand is why there is no leaking when the hose for the primer bulb is removed. It runs great and does not leak at all with it removed. Put the hose back on and it leaks when running and when off.

I would agree that does not seem to make much sense, however not knowing what model engine or carb you have, I can not really provide ne help either. The manual I posted a link to is a complete service manual for all models 3 to 11HP. You should find the info needed there. Perhaps replacing the primer bulb itself.
Or post the model # of your engine.

Remove the float and shake it near your ear. If you hear gas sloshing in it, it is bad and not floating in the bowl to shut off the gas.
