Recently had the throwout bearing replaced on my 1950 Farmall Cub with a 12v conversion, but since returning it is running very poorly. It starts, but acts like it is only running on a few cylinders and only seems to run smoothly close to idle until warmed up for 20 minutes or so. When advancing the throttle it will immediately stumble and then run and miss erratically. Any choke after running a few minutes seems to immediately kill the engine. The governor keeps trying to adjust the carb between the hits and misses.
So far I"ve replaced the distributor cap and rotor and all the plug wires. The plugs and points were changed last spring, and the fuel line replaced and a separate inline fuel filter eliminated at the same time. The carb was cleaned then as well and the gaskets replaced. It was running fine through the summer until the throwout bearing broke. Any thoughts?
