Picked up this Cabelas (Weston rebrand?) Stainless Vertical Propane smoker for a song and a dance....ok maybe no singing or dancing, but paid $60 for it with a full tank of propane and cases upon cases of various wood. I think Cabelas sold them for $400-$500. For the life of me, I cannot get this up to temperature and hold it there. It simply will not go past 175 on the highest flame setting unless i get a raging fire going in the box. I've tried every combination of vents opened/closed. There are two intake vents, one on each side and an exhaust vent on the top. One thing I noticed, the difference in flame size between LOW and HIGH is very small. Leads me to believe a problem with the burner and/or regulator. I tried a second full propane I had...same thing. I added a few fire bricks to the bottom to retain heat, that helped a little but still not where I want it. Should I consider upgrading the burner/regulator assembly or is there something else? I notice the door leaks a bit and it has no fiberglass rope around it, so I'll be ordering some of that today. I did a brisket and kielbasa over the weekend....brisket got to 155 degrees and then hit a wall. Finished it off on the grill. Kielbasa finished and was outstanding. It's a nice unit but it needs a little help, any recommendations?
