I have a LT 155 that won't start. It has a Kohler CV15S engine. I have 100 PSI compression. As you crank it goes to 30, 60, 90 + PSI max . Checked the fuel pump for flow. Removed and cleaned the tank. New Fuel filter. New ignition coil. Removed the kill wire. Set to .005 gap. Has spark. Even tested with a functioning coil off another tractor . New Plug. Replaced the carb. Changed the filter and replaced the oil. Even with starter fluid she will not kick. . . Get a good backfire a couple times. Any ideas? I'm at a loss.

i would check the flywheel key, if it is sheared, that will throw off your ignition timing.
I pulled the flywheel to check the stator. All looked good.

check the timing key again.
No need to pull he flywheel, just undo the nut / bolt and check that the 2 halves of the keyway made a perfect square.
A single backfilre can cuse the key to shear.

You hit the nail right on the head ! I pulled the flywheel to clean out a mice nest. When I put the flywheel back on I must have pushed the key out .
Put it back in place and re-assembled. She started right up and runs like a champ. This was a curbside find. I enjoy reviving these things.
Thank you for your help! Much appreciated !
