I’ve been having chronic carb/fuel problems for over a year now as noted here:

Most of the time the tractor has been setting up in my shop without being used as a result of these problems. Recently, I am in a bind to get this thing going and have done the following:
1. Thought I had it all figured out till I discovered oil volume was increased (again)
2. Tried to move tractor to shop for work and it wouldn’t start
3. Dumped oil and discovered it was grey with coolant
4. Towed tractor to shop and replaced head gasket (and any other gasket I could)
5. Added new O-ring to the valve at the bottom of the tank (it appears to be holding)
6. Added manual fuel shut-off valve near carb to prevent losing all my gas again
7. Replaced battery, coil resistor and coil and got it running again (albeit somewhat rough)
As of right now, fuel flows out of the carburetor if I leave the valve open when the tractor is not running. It does run (poorly) and I can move it around and “use” it, but there is obviously a major carburetor problem. Before I reinstalled the carburetor, I had blown into the fuel inlet line while the carb was upside down to see if the float would seal up the needle/seat and it felt like it was making a good seal, so I don’t understand why it is not now sealing now that it has gas in it. I don’t think it is a problem with the float becoming filled with gas because the fuel was flowing out of the carburetor within seconds of filling the carb up for the first time. It simply is not shutting off the flow of fuel. I guess my next step is to rebuild the carb again, but my lack of success on the first rebuild has me feeling unworthy to the task. Is there something I may have done wrong that you can think of?
