Thanks for the encouragement guys!
I'm sorry to report that progress has been slow. For about 5 weeks my M-37 has been at the shop getting a little bit of work done. Fuel line replaced and carb cleaned up (going for a re-build in the spring, so gas doesn't sit all winter), now the stalling and hesitation issues are behind us.
Got the steering box seal and lower cover ordered from MWM, and new valve cover gaskets to stop the oil leaking. Should be done this week or next week I HOPE.
Told the guys no rush thats why it's sat so long. They aren't charging storage, and I've been super busy with work, no time to play. When it comes home, it'll be put into storage for the winter.
Having my friend weld a piece of the PTO back together this week it looks like. I've been able to acquire a Braden MU-2 winch off a civi PW, and I think I'll be using that instead of the LU-4. Personal preferences, I've used a MU-2 quite a bit at work and its pretty robust.
Hopefully more updates coming down the pipeline!
Happy holidays!
