With a lot of help from friends I dug into the old tractor this weekend. Compression tested at 50 PSI on the best of the four cylinders and around 25 PSI on the worst. A good six hours of work and we had the engine off the tractor and torn down, that’s a pretty solid six hours with three and some times four people working on this. My Uncle Harold says he doesn’t recall much better than 25 PSI on any cylinder, maybe that’s why it started sort of hard.
Thanks to Harold, Mike and Carl for helping with this project.
