Hello All
I have Husqvrana lawn tractor with a Kohler Courage 21 engine. The engine died abruptly the other day while mowing. It won't start and cranks very hard, keying the ignition switch just moves the flywheel a few teeth, I have to do that several times then finally it makes one complete revolution then refuses to turn again and I have to repeat the process. Carb either pops or backfires when it turns through the complete cycle. Have air cleaner off so I can hear and feel air being pushed out the carb. The big key holding the flywheel is intact, but I don't know how to check the internal woodruf key on the crank.
Battery is good, as is fuel and spark. I am guessing this is something valve related, but something more than just needing valve lash adjustment. It was running fine right until it died, then nothing.
Any thoughts or suggestions are welcome.
Thanks.
John
