Ive got a wheel horse tractor with a Kohler K181 that I'm having trouble with. The tractor is probably late 70s vintage with 12 volt coil ignition system. The thing has been hard to start for years now. Even warm you have to mess with the choke to get it to fire and it just doesn't start well. Once its running though it runs pretty good. So about this time last year I decided I would take the carb off and clean it and rebuild it. Let it soak in chem tool for a couple weeks and blew it out with carb cleaner. It didn't look that bad from the start but I figured maybe something was gummed up. New needle and seat, new bowl gasket and put it back together. Could not get it started after putting the carb back on. Today I put new points and condenser on it and set the points to start to open when the s mark on the flywheel lines up with the timing mark. Finally got it running after sitting for a year but it still doesnt want to start even warm without choking it and cranking like crazy. Even with a shot of ether its hard to start. It has strong spark too and the spark plug is in good shape. Starting to wonder if it maybe a compression issue? Was reading that these maybe have a compression release on them? I'm not really sure at this point. I think I will check the compression with my compression tester but what kind of numbers should I be looking for?
