Small Engines (Lawn Mowers, etc.)/have been talking with you about 40" Murray Mower with 12.5 power built Briggs and Stratton engine that won't start


I can't turn the fly wheel by hand when I have disconnected the spark Plug.

Sorry I had to contact you this way, the original question and answer site wouldn't let me answer your question.

Thanks for your help!!

Did you remove the spark plug from the engine?  

With the spark plug removed, you should be able to spin the engine by hand.  If the spark plug is removed, and you can spin the engine by hand then the starter will not be able to spin the engine.

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.
