Something I've seen a couple times now and I know a couple others in the thread have mentioned it: When you start a game, the jetpack is supposed to index out from its home position and allow the ball to come through. He'll stay indexed out until you lock a ball for jetpack multiball, at which point he returns the short distance to home and the magnet fires and picks up the ball. Occasionally on my machine, Bond fails to index out and stays in his original home position - which makes a mess since balls shot around the upper jetpack orbit hit his feet and either get trapped there or fall off down to the shooter lane, etc.
George explained that at the bottom of the main jetpack assembly, on the motor side of the belt drive is a "clutch" of sorts, using a belleville / wavy washer. He answered my question about this on the stream last night and he recommended tightening the bolt on the end of that shaft (part #6 from Stern's manual below) to compress the wavy washer a bit and that this should clear up the issue. I did that last night and haven't had the problem repeat yet. But I also haven't played a lot of games yet.
I assume the purpose of the clutch is to keep the mech from breaking or from snapping Bond into pieces if it were to get hung up during its travel, so it seems like something you should only tweak if you have a problem and in my mind, only tweak a little to avoid losing the compliance that the clutch provides. I tweaked it about 1/8 turn tighter. The clutch bolt is easiest to access with the playfield flipped up vertical against the backbox.
