Referring to your picture:
The natural resting position of the sector gear chip is at the 10-11 o'clock position so that it is retracting the tappet plate which pulls the nozzle back and it's ready for feeding. Right now it's at the 4 o'clock position. Iirc the notch that engages the cutoff lever is at the 6-o clock position, which means you need to rotate the gear counter clockwise to the 12 o'clock position (pushing just before engaging the tappet plate" in order for it to engage the cutoff lever to push up that arm that interacts with the trigger shuttle.
This is NOT enough clearance because the gear needs to be at 11 o'clock and not 12 o'clock:
Pic for reference:
so you need to shoot full auto to hopefully put it back in the into the right position and once it cycles the cutoff lever shouldn't interfere with the trigger.
Note: v3's are known to misfire if you shortpull the trigger on semi and this is the result. I just remembered the v2 trigger is 1 piece versus that God awful v3 rotating POS that has 2 moving parts instead of just 1. This is why this happens.
