Last shot was when the piston was held back to probably the last tooth after being on full-auto, and then switching to semi which is why that sounded so crisp.
The bushings were press fitted but because they weren't flush w/ the gb i had to press them out... then I realized that they were too tight to go back in so I filed it down and now they're too loose. I think these are 7mm bushings, not 6, like most of them are advertised; so now i have a pack of bushings that are too small.
I'm probably just bad at shimming, no other way around it but I'm guessing them being stock gears don't help. I can't seem to get them to spin freely on their own with no load even though the gears aren't grinding on each other and not enough shims to cause seizing...
In some videos I see gears doing 3-5 rotations with all 3 in an empty gearbox. Mine will only do 1 full rotation when spun by the sector gear.
