Exhaust is not smoky but it does smell fuel rich, but not bad. I tried to lean it out a bit with the main jet adjusting needle. Oil pressure with warm engine is still good, 40+ psi at WOT. 20 psi at idle. The tractor was neglected for some time. The air cleaner was full of sludge, engine oil was black with sludge around the screen when I drained it. Oil filter canister was sludged up as well. Spark plugs are AC Delco. I do not remember the number on the plugs and I'm out of state right now and can't check. My plan is to run the tractor for awhile and treat it right with regular service and maintenance before I do anything drastic. A compression test was next on my list to do. Then after a full season of work and proper treatment I will do another compression test to see if there any differences. I've ordered a carburetor overhaul kit and a parts manual and shop manual as a start. Brakes need work as well as steering adjustment.
