Coyote, the 1020 was built between 1965 and 1973. It definitely was designed to run on leaded gas.
duke, One thing I would like to add is the brand of spark plug. Right around the same time leaded gas disappeared, I stopped having any luck with Champion plugs in these JD utility tractors. I switched to Autolite and had much better success. Have you tried adjusting the carb at all? The needle valve screw near the top of carb adjusts idle mixture. SInce it is loading up at idle, I would try turning that screw in maybe 1/4 turn to see if it helps.
I changed the plugs with autolite and it appears to have done the trick. Running like a Deere again, thanks for the tip.
