I just acquired a 1994 Timberwolf 250 2wd. Drove fine at seller’s property. Got home, I started it, put it first gear, shifted to reverse, backed out of trailer, moved reverse shifter back forward, then nothing. Throttle revs but doesn’t go anywhere. The shift lever doesn’t really feel like it’s going through gears. I can roll it manually forever so I’m pretty sure it’s in neutral, but no neutral light. Then I decided to try reverse again, and, it goes into reverse. And drives in reverse. But as soon as I take it out of reverse, it rolls freely again. I can’t get it into any forward gear. The seller has owned it for 20 years (60 year old man). He didn’t have a manual so I’ve ordered a Clymer (I’m old school paper in my hand reader). Outward appearance is very good. Any advice would be greatly appreciated. Thanks
