Simple remedy for more smoke. Use a smoke tube or sprinkle some hickory chips onto the drip pan, near one edge. The temp should be enough to make them smoke. Smoke tube works better. Keep in mind that the white smoke you see is not the ideal smoke, it is the blue smoke that is harder to see that renders the wood flavor. I use a hickory pellets (B & B) that are not all hickory. Lumberjacks are 100% and that may work better. I just made ribs on my GS and they were wonderful, and mildly smoky which is the way we like them. I cook em at 260 so I don't see a lot of smoke. With the smoke tube, they are much smokier, but we decided that we were happy without the extra. You have a great pit by history, so I'm sure you can obtain what you like with some manipulation as above.. Good luck.
