I recently tryed to overhaul my motor. When i took it apart the cylinder wall was scored up. I took it to a machine shop and they reamed it out to 30 thow over size. i put a new piston in it and because this is not the first tim i did this job i cleand every thing up and put it all back to-gether again.Timed it properly made sure the slinger was lined up the sump went on easy and every thing seemed o.k. It run good for about an hr.or maybe two then i stoped it for a break. When i tried to start it again it turned 3or4 times over than seazed up. So i took it apart again the piston was seazed in the wall. there was a ridge in the wall.I honed the wall out cleaned everything and put it all back to-grther again.It did exacly the same thing.Can any one shed some light on this problem .Its 19407 4017-01 I have done a few of these before.
Thanking you in advance Ross
