Okay, you're not the first to suggest this. And I know Drew is laughing his
ass off if he reads this  (and he's always saying it's a skinny ass too, so
that should be a short laugh) Okay, assuming that I am installing a cap for
the first time, what is the correct method? I've had the cap on/off a few
times, and tried a different cap too. So maybe I just cannot install a cap.
There'as a little tab that engages the distributor housing, if it it's in
the spot where it settles into that notch, and I do up the clips, that
should do it? Yeah, I'm serious. I'll check ANYTHING at this point.

Well, Dan and I did fiddle with this angle at one point, though it's back
to the original -10* now I think.

Well, how does CIS-E sit with you? Or compression ignition? Honestly, at
this point a diesel swap may have been easier. But agreed, I'd still like
to see it at Cincy too. The MS part has been the easiest part of it. It was
the injector seat swap that was the doozy.
Keep suggestions coming.
