All engines wear the piston and bore more on the thrust side of the cylinder.  The thrust side is always the side of the bore that is counter to engine rotation, thus the valve side on a Kohler.  This is phenomenon is common to all engines, whether single cylinder, multi-cylinder, or any number V configuration.

ok thanks. I guess it'll have to be rebored don't ya think?

I can't say for sure, but I think it would need to be bored. I took the head off a K241 in one of my MM last week and I noticed that I could see the rings also. It seemed as though I could move the piston around about 1/16". It did run but I figured it should be checked and probably rebuilt at that point before something gets wrecked.

On a different MM I have, the exhaust valve and port was so rusted that the valve broke when I tried to loosen it. I soaked it in transmission fluid and cleaned the port, put in a used valve and set the lash and it runs great.

Well now the exhaust valve is free. A little Marvel Mystery Oil soaking on it freed it up real good. Now I can get it running to see if the hydro and electric pto is good.

The trigger module looks pretty new. The ignition coil shows how i fixed it with some soldering and a zip tie just to make sure it dont get broken again because it took awhile to show it.

Low compression can be many things. Leaky valves, stuck rings, head gasket. Are those 2 studs that corroded near the block or is it just the pic?

The coil fix looks good.

If you get it running, put some Marvel Mystery oil in the gas & oil. No more than 25% in the oil, I usually stay about 10-15%. That will help loosen stuck rings and clean the valves. Also clean out the crankcase.

I know how you feel. Sometimes you need to take a break from it for a day or two and start fresh.

 

What makes you think it has low compression?

im getting fuel and spark. exhaust valve is closing but maybe it needs lapped since it was stuck open and might have rusted?
