My curiosity got the best of me today, and I pulled off the head. Not what I was hoping for!! It looks like it will need to be sleeved. I don't think the .5mm oversize piston will even come close to cleaning up. Plus there are some odd horizontal marks on the cylinder that may be cracks. Now what to do??? Fix it, put it back together or purchase one of these V2203. I had one fellow tell me not to use a reefer motor. But I am sure most of the used ones out there are from that application. I believe he said it had something to do with the governor. I also remember seeing something about the rear engine mount plate doesn't fit the v2203, but the flywheel and starter will. Not sure what that's about.
