At the risk of pissing off one of the old timers for asking a question that's already been addressed in the Stickies, I need some clarification on the procedure that William1 posted for adjusting the AP. "Accurate" route As directed in the post, I held up the slide with an 8mm blank and backed out the AP adjustment screw. However, when we are talking about "Turn the AP timing screw so the play just barely goes away." Are we talking all the way IN or OUT? Because if I turn it all the way OUT, there is no end to the "play" unless I raise the slide higher. At 8mm, the black AP lever is still leaning against the screw mount (even if the screw isn't in it). The only clear separation between the AP lever and AP screw occurs at WOT. "Not as accurate" route Backed out the idle screw until the slide sits on the base of the bore. However, the "Set the timing gap between the cam and the screw to be .010" again has me confused since I can't get the the AP lever and AP screw to show any light between them outside of WOT. I've looked at a dozen videos on YouTube and have seen the TT video showing suggestions on the 2.5mm measurement, but what I don't get is what is being measured at a distance of 2.5mm??? Are we talking the base of the AP screw MOUNT to the AP LEVER? Or is it the length of actual AP adjustment screw that is protruding from it's mount? Again, for give me for my ignorance (especially William1), I'd just like to get my AP dialed in and the sticky is doing nothing more than leaving me frustrated due to the little bits of info it seems to be lacking. Thanks for the help!
