Due to compression leak, found with leak down tester, I decided to take the engine apart and do a rebuild. This is a k241 out of my Minneapolis Moline 110. The cam has a lot of wear in the area the points rod runsand also on the compression release tab. I have a used cam to replace it with, but has anyone else come across wear like this? This is a early engine, it has a metal governor gear vs plastic.The piston and cylinder had normal wear.
