Reading this thread reminded me that my neighbor gave me a Mr Heater when he was cleaning out his garage. I had no idea it would be so useful for camping till I saw this thread. Anyway, I pulled it out and dusted it off. It looks brand new, but I can't get the pilot lit for the life of me. It has a brand new cylinder, and the ignitor sparks, but no flame. Is it my altitude (6500 feet)? Any tips/suggestions?
