I was once involved with a 971 with a similar problem. It would start up and run OK cold, but after it warmed up it acted like it was starving for fuel unless you ran it with the choke half closed. You name it, I tried it, including having the fuel tank boiled, carb professionally rebuilt etc. I was convinced it had something to do with the proximity of the exhaust system to the fuel system 'cause it always ran great in the winter. Someone insisted it was vapor lock, but how can a gravity feed system vapor lock? I rerouted the fuel line as far away from the exhaust components as I could to minimize the possibility of gasoline boiling or vaporizing in the fuel line, but it made no difference.
I cussed that thing for 5 1/2 years, and when I finally quit that job and moved on we still didn't have it resolved. (Though that wasn't the reason I quit that job).
Sorry I can't help. Actually, I liked the tractor. It had SOS, and in the summer we ran it on a 7', dual blade finish mower. You couldn't have asked for a more ideal combination of tractor and mower.
