It does dance, and even jumps a little--but it doesn't blow off. From that I'd say there is a little blowby, but it's not at the end of the road.

It is a wear point and also has a critical rubber component that deteriorates over time from heat and oil exposure. Look it over carefully. It is an inexpensive item to replace.

I think that particular pivot mechanism is ok, at the very least the accelerator pedal can move the linkages far enough to engage the kickdown button. But it seems likely that my linkages are all out of whack, everything seems to be "hanging" off the linkage to the injection pump--and the IP linkage can't move anywhere close to its maximum extent. But I'm not going to get into the linkages until I understand them a little better.
Edit: Wise to not just start adjusting, the linkage is hanging up on the cruise control, not the injection pump. Yikes, what a mistake. In any case the cruise control linkage is clearly wrong and may be interfering with other linkages working correctly--and possibly preventing full travel on other linkages. I feel like I'm probably safe to adjust that one.
