smoker built from air compressor tank or LP tank?

The elbow may be restricting plus I think your stack may be too long to draw, best bet would be to check out the pit calculator and see if your numbers are correct.

If you end up replacing the stack, I would shoot for a  a 4" stack or a 5" stack, straight out of the top or side with no bends.

You could try taking a foot off of the stack and doing a test burn to see if it brings the heat up.

IIRC for an 80 gallon tank and a 4' stack its 25- 26" high, I just did a test burn on mine.

I loaded up the firebox with 5 logs and fired up the pipe burner for 5 minutes, after about an hour I had it up to 450 degrees.

Do you have the wood raised during a burn?

Does your stack go to grate level?

Wood is raised off of floor by 6 inches with a 3" intake on one side and 2-3" intakes on the opposite side. The stake does not go to the grate it is 6" above the grate. this was my first build and not knowing any calculations i quessed at it. I thought raising up higher the smoke would not be at my eye level.

Seems like your firebox is ok, If it were me, the first thing I would do is change the stack.

Here is the Pit Calculator, check to see if your stack falls within the suggested range.

Looks like the pit calculator changed quite a bit, I have a copy of mine on my blog at the top
