I've been modding a Umarex/Elite Force TAR-21 for the past few months. I installed low-profile bushings (the gun had bearings), SHS 13.65:1 gears, an ASG Infinity Boost 30K RPM 16TPA Short Motor (high torque), a Raptors piston head, and a stock G&G piston. I also shimmed the gears, adjusted the motor, and did an AoE correction. I left in the wiring, cylinder, cylinder head, tappet plate, and nozzle.
(I plan on replacing the wiring with 16awg wire and a Gate NanoASR mosfet, but that's another discussion.)
When I put the gearbox back together, it won't fire, or it'll get stuck halfway and lock up, and then the wires and battery get hot and I have to disconnect them. This happened with the new piston/piston head I installed, and when I put the stock piston/piston head unit back in to test. Oddly enough, when I accidentally left out the piston and spring, the gears spin freely and move the tappet plate/nozzle.
If any of you have any ideas on what might be causing this, I'd appreciate any advice/suggestions. I can provide pictures if necessary
