I inherited my first Wheel Horse, an 312-8, from my brother, who happened upon it in his travels. It didn't appear to have been run in some time as it sat outside with weeds growing over it. After about 30 minutes we had it running. Needed a new fuel pump ($17), fresh gas, and a little WD40. We spent a good couple hours freeing things up and putting tubes in back wheels and she runs like a top. More to come...
