Iam not sure on the double pumper, but for starts do you still have the p0ower valve in?

Iam currently running 73's in the prims and 65's in the secs. I have my power valve plugged so I need to have richer jets. If you have the power valve still in, I think you sre supposed to run 8 sizes leaner? About, give or take. I have heard of someone running all 68's and supposedly ran good?

Lately I have been playing with my idle mix screws and it seems to run better being leaner about 1 turn out. I used to have it 2-2.5, but dont know still playing with it. Iam trying to get out to lakeland fri night, run a few times, I am hoping low 9's with my muffler on?
