Thanks guys!
I think I just needed to shut the vents down more. It ran at 250-275 for a couple of hours, then seemed to settle in at 300. I closed them a little more then half when I noticed it creeping up, maybe even more than that though.
Not too much smoke for my taste, but I might like it a little heavier than most. Plus it was apple wood, probably wouldn't have used that much if I was using something like hickory.
Thanks again for the comments and inspiration
