Remove air filter and pour a small amount of gas directly into the carb. Try syarting. If it runs then dies off you either need a carb rebuild or you have no fuel getting to the carb. Please be careful as if it backfires the fuel can catch fire. It only takes a very small amount...a teaspoon or so for this test.

Is the spark plug wet, or is there fuel leaking from carb.
Check shaft on engine while cranking, does it move.
Also check kill wire on engine.

I would check the big three first of all. Spark, compression and fuel. Sounds like you have spark and fuel. I would get a compression tester to check actual amount of compression. If all three of those things are good I would check valve lash. You will need make, model and serial number of engine. If you post these I can help find specs for you. Good luck.

Check you fuel cap vent.

unplug the connector from the side of the engine and try it if it fires on starting fluid then the problem is one of the safety switches

Sounds like its not getting enough fuel. clean the fuel system and the carby. The valve clearances also need to be checked.

Try cleaning or better yet, replacing the spark plug. Depending on age and how your tractor was maintained, there are other possible causes.

• Gummed up fuel system
• dirty fuel filter
• defective or misaligned armature/magneto (part that causes your plug to spark, igniting the air/fuel mixture, thus starting the engine)
• throttle linkage/cable problems
• low oil level. Some Kohler engines use a low oil shut down sensor which won't allow the engine to run or start to avoid internal damage.
• Mechanical engine problems

I hope you find this solution helpful. Please rate it thanks for using Fixya!

Check your spark plug. Or maybe your choke is stuck

check to make sure you are getting fire
