mine is set up the way <FONT face=Verdana size=1>Kahnman decribes his the problem is its most likly still leaking at least mine does, its just cumming up at the needle under the slide. I have to rap the throttle to get some response out of mine.

This is also what I know beleive to be causeing my low rpm plug fouling issues. I'm giving up on this carb for awhile. </FONT>

 

i can't understand what you're saying about the pwk like a junk carb,
i'm so happy with mine,it is best running and so easy to tune,
i have 170 main and cannot even reach 1200 on top,i can even drop to 165
main with race mods on very hot temp with this carb,that not joke,best top end power out of this motor,,the pwk 39 (i owne the race unit) doesn't leak as the first i bought from hpd.
