Got a 4020 gas, acting up a bit. When I have been running for an hour or so in the hay field at temp, it starts to lean out, so I tug a little on the choke, it runs fine, then after a while it almost dies, and I limp back to the house with the choke fully pulled. Already flushed the tank, carb is clean (Zenith). The fuel line seems very close to the block and was very hot to the touch, carb seemed warm too, warmer than a coffee cup. Is it a fuel delivery issue or a fuel metering issue. Been several years since I put a lift pump on it. I am thinking of pulling the fuel line away from the block as far as I can, maybe insulate it with left over fiberglass header wrap.
I am open to ideas. Tractor runs great when cool
Temp outside today was 85, no wind
