One of the things, which I would look at is :Where is the fuel line positioned, in relationship to the exhaust manifold? On my NAA, the gas line was fairly close, and behind the exhaust manifold. It ran fine for 50 years, until they changed to ethanol fuel .... ethanol boils at a lower temperature than regular gas, as a result, when the tractor got hot, it was "vapor locking" ... it wouldn't even run right with the choke out. I wrapped the fuel line with fiberglass stove seal rope and have had no further problems. ??
Son of a gun, I never even thought of that. I will give it a try and report back.
Thanks,
Sincerely,
