Today, I looked at an old rusty Hyster forklift, powered by a 230 Chrysler industrial engine. It's been sitting in a junk yard for 6 years. It's on propane, still half a tank of gas in it. We put a battery in it and it started! The oil looked new and the radiator was still topped off with green-looking antifreeze. In a few minutes it was warmed up, idling quietly and smooth as silk....just like someone had been using it, just yesterday! There was no smoke,or unusual noises. Man, for a hundred bucks, I don't see how I could go wrong! Only problem is, i have to pull it where it sits, transmission is shot and the wheels are sunk into the dirt. Oh well, I'm retired and have nothing but time!
