I've got a 610 with a motor going bad. Anybody ever replace a wiconsin 4cyl. Did you buy a new motor, a rebuilt one, or replace with a different motor or am I better off getting a different loader. I know I can get rebuilt for 3500$ plus. They say I can replace with a new 35hp vanguard motor. Any thoughts would be appreciated. PM me. Needless to say I'm looking for a different loader, a 610, maybe a 743. Or if someone has a good motor. Let me know. Thanks Rod in Kansas
