heavy bog under acell

Yeah one of my first thoughts was the pump shot, I adjusted the arm, my question on that is it you want to see a .015 gap when WOT and pushing down on the lever. I'm gonna try and go up a couple sizes on the power valve and see what happens. I will also check plugs and see how they look. As far as the vacuum pod right now it has the plain spring which I think is the middle one. I'll check for vacuum leaks as well. Thanks for the suggestions I will keep you posted.
