I’ve seen some of those motors with a worn upper crankshaft bushing/bearing. I have a 1 1/2 Mate that has this problem. It runs good once you can get it to start, and will only idle fair at best. That will make them tough to idle down. Grab the top of the flywheel and see if you can move it fore and aft, then try it left to right. Be sure the flywheel doesn’t rotate while doing this test.
