Small Engines (Lawn Mowers, etc.)/kohler engines


QUESTION: while cutting my grass my craftsman zrt 0 turn stopped running and will not even crank over. it is froze wil not free wheel to cycle at all

ANSWER: Did you remove the spark plug(s) and try to see if the starter will spin the engine?  Can you spin/rotate the engine by hand with the spark plug(s) removed?

What is the Kohler engine model and spec number?

You can download the service manual for free from Kohler's website.

QUESTION: started tearing down engine. the engine would not turn by hand in the proper direction. But after trying to reverse motor by hand it did turn over and even crank. there is no compression at all. so I am going to continue to tear down and see what all broke

Did you download the service manual?  One trick to see if the piston is moving, without removing the head, is to use a drinking straw and insert in the spark plug hole.  You will be able to feel the piston move as it contacts and moves the straw.

Let me know what you find.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
