I prefer diesel power as it doesn't care how long it sits around not getting run much. Gas gets stale, even with stablizer in it. Carbs foul and go lean. Give me a diesel any day. This is why I built my little diesel powered Wheel Horse. While I have the mower deck for the Massey, the special cast cogged pulleys are eroded away and nearly impossible to find. So the Massey will be a plow day only machine. I even got a sleeve hitch he started to adapted to the tractor. So I can finish that up and be plow day ready once she runs. I do plan to get the Kohler running as it was supposed to have been rebuilt about 6 years ago, then left to sit. I want to get it running so I can sell it to help fund the diesel engine.
