Craftsman LT 2000 Wont Start

Craftsman LT 2000 Koeler 17HP OHV 6-7 years old. Tractor has been running fine all year. This weekend, I tried to crank it and ignition sounded fine. However, engine turns over but wont start. Thought it could be fuel problem. Tried starter fluid in carb but this did not work. Replaced plug, fuel filter and air filter but did not help. Oil is fine.

Noticed last time I ran it, the engine backfired but I did not think it was a problem. Also, when trying to crank now, I do get a slight backfire when it is trying to catch..

Any idea what might be causing this? Rings? Expensive?

Pull the valve cover off and see if the pushrods are still in place, check valve clearance.

check for spark, and for compression. the fuel but you are spraying it with starter fluid so when all is good it should fire.
It should be hard to hold compression on the motor. If all else fails check the shear pin on the flywheel, this will cause it not to start and backfire and such.

I had a Kohler that acted like yours with the back fire and for some reason sheared the flywheel key.

I agree... check the flywheel key.

It was the flywheel key. It had sheared. Good to go now. Thanks to all of you!
