Question?

Will changing the height of the chimney cap affect the intern temperature or smoke level?

 

[Shedd]

I’ve had mine turned really close to being closed, probably 1/2”, for close to a year now and it’s been a more consistent temperature inside. When using my smoke tubes I can really notice the difference in the smoke taste. I also added a gasket to the door and I lay a concrete block on the handle to weight the door down so it keeps the smoke inside better. I’ve actually got a spiral ham on it now.

 

[Like Smoke]

I do the same thing Shedd does, I have about a 1/2 inch between the cap and stack. You don't have to worry about restricting the air flow because any additional pressure exhausts thru the square tube that is above your grease catching bucket. If I was to redesign mine I would move the stack cutout down to half way between the top and bottom of the tank to allow the heat and smoke to spend more time on the cooking surface. Welcome to the site, good folks and really good recipes.
