Had to replace the regulator on my MrHeater buddy. It got to where it would shut off after 5 or 15 minutes of run time. The pilot flame would dance around and sometimes shoot a flame an extra inch or so, or die down to just a flicker. After ceaning the lines of any possible contamanits. I did a little research on line and took my best guess. I got lucky. I guess that's what I get for running it on a 20lb tank with no filter. I order 6 yards of ripstop nylon, so I can cover most of the breathable mosquito netting on my tent. I figured I'd set up the tent around Christmas break and see how it all does in cold weather. It would be nice to break the chill in the mornings before climbing out of a nice warm sack to get dressed.
