A neighbor gave me this unit. Has a Kawasaki engine that he said just quit one day and appears to be locked up. sorta. When starter engages, engine moves slightly then stops, like something is in the way. I may try to repair it, or might just do an engine swap. Any guesses what this could be? I haven't done anything yet and will probably let it sit until time frees up a little, but I will be thinking all possible reasons for this problem. Trying to remember what engine looks like, OHV with two valve covers for sure. Beyond that I don't remember anything about engine. Also wondering where model and ser#s are located. Most likely will be giving thoughts after pulling covers up at night. LOL My first ever Kawasaki engine.
