Here is a video of how the PWK works on a normal freeway merge. It runs smooth, pulls hard, and revs willingly. No hicups or hesitation, no misfire.

No add-on power jet or intelijet or thunderjet or dial-a-jet. Just regular tuning. It ran pretty much the same with the .075" air bleed too. If your carb doesn't run similar to this, then something isn't right. You shouldn't need a more restrictive air cleaner. That's moving backwards, depriving the engine of air. I have a very large K&N air filter. It works fine. It is possible to force a carburetor to work a bit better by restricting the air filter, but that's simply covering up the real problem.
If you have a #7 slide, a .110" needle jet, a .075" main air bleed, and that DGK needle, it should run similar to mine.
How did you install the carb? Is it on the stock manifold? If it's on the stock manifold, did you replace the stock clamp with the special Ideal clamp? Have you checked the manifold for air leaks? ThumperPaul had a lot of trouble with his PWK and it turned out to be a leaky manifold.
