Got an old (late 1980's) Kerosene, Koehring, Wind O Heater, Model WV-50B heater for my garage for a good price (free). Lady tells me "it worked when we shut it off"--before her husband died. But, it won't work for me. It seems to have a leak in the fuel pressure regulator. Will fire up once and then won't relight and the safety reset is popping. I can't find anyone who carries these old heaters, did carry them, or knows anything about them. I've already cut the hole in the garage wall and inserted the darn thing. Anyone know anything about these things, or where to talk to someone about them or get parts etc. etc.??
