I was given a walk behind MTD Yardman. It starts with a new plug and has run intermittently since I picked it up. I finally got tired of killing myself every time I mowed my lawn (1+ acre) and decided to tear into it and see if it's worth repairing. All of the decals have worn off and I didn't find a serial # on the engine. The guy who gave it to me said he tipped it on its' side to sharpen the blade. The piston and valve heads show a lot of carbon build up and oil definitely got into the cylinder. The cylinder itself was smooth. Judging by the photos, what's the best advice for finishing up this project without spending more than a new mower would cost me? Also, I managed to break off one of the bolt heads that holds on the valve cover. Am I screwed?
Thanks for any help is greatly appreciated.
