Mr. Heater Little Buddy not lighting

[GIL HUNTS]

I carry a $1 propane lighter to light mine the old fashion way if it doesn't want to act right.

Smart, I’ve got a Mr.Buddy that’s been giving me some problems. I have it hooked up to a big tank. The pilot will light and stay on forever but as soon as I turn the lever to low or hi it will burn for a minute or so and turn off. Unhooked the big bottle and out a small green one on it and it ran just fine. I know the big bottle is full.

Sounds like your regulator on your big bottle is jacked....or your hose is clogged w/ oil leached from the hose. Don't run a big tank without the filter. The oil will clog the lines.
