when you adjust the floats make sure there even. if ones of it will screw it up.
as for the powervalve, that really couldn't be the problem. the linkage on mine came apart and wasn't hooked up anymore and still ran fine. i didn't even notice anything was wrong until i looked on the inspection window and saw the bolt missing along with a bunch of the other parts. the tranny gears had some nice stell parts to chew on!!
