i did a batch of venison bacon last wk , it was abought 20 deg out and handled it quite well. just ran it a little hotter than norm.but i do think i may be starting to have regulater problems.i might have to replace mine am having a hard time keeping a flame at all.twards the end of my cook i had to switch tanks about 3 times. it was reall strange id switch and burn good for 1/2 hr and lose pressure switch again and burn good again .almost like it was 40below with tanks freezing up any ideas?
