I know I've been mia for a while, so it's good to be back. I was looking at a Massey Ferguson 10 on Craigslist, but it has the Techumseh HH100. I have had much better luck with kohlers and just so happen to have an extra K241 laying around the barn. I was wondering if you guys thought it would be super difficult other than the obvious ( changing wiring and ignition switches) to swap out the motors.
