Ok, no matter what I do, how many times I adjust it, my idle keeps on creeping up over days/weeks. The only way I can adjust it is by turning the max fuel screw down. I have done this 4-5 times already. Oddly enough, I don't thing it has really changed my power, at least that I can tell. Mods to the pump(AAZ) are I have shimmed the main spring, 10mm head & cam plate from Prothe, and I made a new shim for under the plunger foot from a grade 5 bolt. Could problems with any of these cause the idle to creep up?
