I can't find the post but somebody mentioned to check for blockage in the burner tube. I found a spider web that was causing my problems. Thanks guys
Mine was full of stink bugs
Is this on your propane fridge? I had to blow my tubes out a while ago when I was getting a dirty flame and the fridge wasn’t cooling. Probably had something to do with the fact that we were camping at >7,000 ft elevation too.
Same with your barbecue as well they’ll get spider webs eggs in there whatever too
