The crank was good so it went back with STD bearings. Top 2 rings are gapped 180 degrees and parallel to the crank shaft. Oil rings are at 90 degrees to the crank. I will be doing new guides and valves and lapping the seats.

Re: AHRM48 mower deck

Tim, I had never thought about putting the Burco blower on the 4118. The blower would need a pressure relief valve added but that would be a quick fix. You have given me more reason to work on putting the dishevel tractor back into shape.
