Thanks for the quick hits on the thread guys, appreciate it.

Fully charged 8.4 1400mah minis. I have 4 of them and have been trying them all out during testing. When the gun quit at the FTF game (before we even got started), I used 2 of those batteries in my M4 and they seemed "normal".

Yeah, the tappet plate thing is hard to describe. When non-tensioned assembled, and the mechbox open, when I manually rotate the sector gear, the nubbin will engage the tappet plate fin and start to move it back. Just when it starts its downward travel (around 11 o'clock-ish) it seems to run out of room (i.e. the tappet plate is all the way back, nozzel flush with cylinder head front face and edge of cylinder). Oriented with the left side of the mechbox laying down on table, nozzle pointed right (just like most pictures). The left/rear end of the tappet plate has to bend up (i.e. into where the cylinder/spring would be) for the nubbin to clear and finish its rotation. It seems to be excessive.

Assembly hasn't been a problem, fiddly and a pain but normal. Things seem to go together with that satisfying "click" where everything "feels" good. Hard to describe. When assembling, I've tried to keep the nubbin indexed at 1 o'clock, but maybe a touch more forward, but so it's just ahead of the tappet plate fin.

I'm wondering if the tappet plate fin is getting jammed between the nubbin tip and the mechbox case (right half). Not during assembly but after it's gone through some firing cycles. I've only got 1 thick shim on top of the sector gear (think it's 0.5mm) and there's almost no side to side play with that gear when the mechbox is closed and screwed tight. I'll check for wear marks on the inside face of the fin when I have it open again (which will probably be tonight).
