I just picked one of these up for a dollar(!!) After giving it a once over I wheeled it outside and fired it off. I scared the bejeezus out of myself when the burner lit, but after a few minutes it calmed down and behaved nicely. Despite semi nasty gas, it seems to run pretty good now. Does anyone know the fuel burn rate for these? I suspect that it will cost me more to run it for a minute than what I paid for it!
