Small Engines (Lawn Mowers, etc.)/Snapper engine won't turn over

Question
Eric, my man!

It works! Took shroud off engine, flywheel wouldn't budge by hand. Tried several times, no luck. Was about to give up, decided to try one more time, it broke free. Turns both directions. Re-assembled, hooked up battery, cranked right up!
But this is HUGE. Won't take up your time with the whys, but I really appreciate it. Wanna take a stab at why it may have been stuck since nothing obvious? I didn't see anything impeding movement, no parts jumped up in the air as I was turning it.

Father-n-law bought this thing for $50 several years ago. Sure has got his $'s worth.

Thanks so much Eric. You're the best.
Don

Answer
Glad to hear it is running...but I've seen this before.

Most likely something inside the engine, either the connecting rod or maybe the upper main crankshaft bushing may have seized slightly.

I would run it till it quits making sure to keep oil in the engine to prevent the seize from happening again as long as possible.

Experience

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.
