Read the spark plug first to try to see what has been going on. A plug in normal condition has a thin layer of light-brown deposits on it. If you see a thick layer of black carbon deposits, it's a sign that the carburetor mixture is too rich -- your engine may even be smoking. Electrodes that have been worn thin are a sign of overheating, often caused by too much ethanol in the gas. If your plug has wet, oily deposits, it's time to take the mower in for servicing, because oil is leaking into the combustion chamber where it shouldn't be. · Other Engine Problems · If your spark plug appears to have normal wear -- or if you've just installed a new one -- and the engine doesn't fire, you can check the plug by replacing the spark plug wire with a tester and pulling the starting rope. If you don't see a spark on the tester, there may be a problem with the ignition coil of the flywheel to which it's attached. The ignition coil doesn't frequently develop problems, but the connection between the flywheel and coil or between the starting pulley and flywheel can wear out, and the coil may not be turning. Replacing the worn part isn't difficult, but you may need a pro to properly disassemble the engine. Answer from mayer on ifixit.com

Kohler engine cranking but not starting | Lawn Care Forum
October 16, 2011 - Checked the schmatic and it is a fuel shut-off solenoid if I am looking at it correctly. I also removed the spark plug and it looks brand new so I sprayed a little WD40 in the cylinder and put the plug back in. It will crank all day but will not fire up. I could not find a reset button on the solenoid if it is stopping flow of gas to the carb.

May 22, 2024 -
Having trouble with my Hustler zero turn.
About a months ago I hopped onto the mower and started it, and I noticed it was hard to start. The next week I went to use it and it wouldn’t start- just crank crank crank so it turns over but never actually fires up. So far I have changed the carburetor, including the fuel solenoid, spark plugs, fuel lines to the fuel pump fuel pump, fuel pump, oil, and gas. After changing fuel pump and hoses and carburetor, when trying to start, it does the same thing. Carburetor bowl fills up with gas just never starts even with starting fluid. I have messed with the auto choke by manually choking. Still, no luck. Any advice would be helpful. Thank you.

If it cranks and cranks, it's clearly (most likely) an electrical issue. Sounds you checked everything, but the one thing it probably is.... the magento. Did you try a spark plug tester to confirm the magneto is actually producing spark?

Will it start on starting fluid? Also check to make sure the fuel solenoid is working, you said new carb but could be wiring/electrical issue to the carb.

August 24, 2009 - You might try spinning the engine over about ten times with the spark plug out and the throttle at full open. That will get rid of the gas in the combustion chamber and may get you going.

Slow cranking, but eventually starts (Kohler) | My Tractor Forum
May 17, 2014 - If you still have the hard starting (and still don't see that little dip of the rocker, you'll need to take the top of the engine off, and replace that camshaft. They use the same camshaft part number for both valves, so you may be able to just swap the cams with each other. If swapping, pay attention to the timing dots on the cam gears and crankshaft because there are dots for the cams being used in either location.

Answer (1 of 12): Your starter motor's gear is not engaging the flywheel's teeth. Starter motor mount could be loose. File this one away: never ever buy a replacement starter motor gear thats made out of iron. Sounds great(!) The teeth won't wear out! Problem is: the teeth on the flywheel ARE N...

Kohler 25hp Engine Ticks But Will Not Turn Over
March 29, 2012 - Have you attempted to manually turn the engine first? It seems like it might be seized or hydraulically locked. Try turning it by hand; if you can't remove the spark plug, be cautious as there may be a lot of gas if it's hydraulically locked. Ensure to avoid any sparks until you clean it up. Place a glove over the spark plug boot and check if it cranks over with the key. If it does, continue cranking until all the gas is expelled, then reinstall the spark plug and see if it starts.
