Finally got off my butt and did this to the #77 IT/HP racecar. Haven't dialed it in on dyno or track yet, just played with the adjustment in the garage. Yeah, definitely a pretty coarse adjustment, but beats having none for so long...

...and it was so easy, comparatively... just as in the pics that Dan posted, but I didn't even bother disconnecting mine, just removed it from the manifold and drilled it on the strut tower by hand. Coulda done it trackside if I'd have been interested (and should've). Since this style has a bolt, and it's the nut not the bolt that's turned to provide the force to move it, you don't need the roll pin described in the original tech article.

But yeah, needs quite a serious whack on the bolt with a hammer to move richer, and a lot of torque on the nut to lean it back out.

A lot cheaper, easier, and faster than an EFI conversion, but definitely just a small bump to the efficiency of the thing.
