Element 300% Torque Full Tune Up Kit (Ver. 2)
I recently purchased this tune up kit. It came with:
Polycarbonate piston head
metal spring guide
torque up gear set
All of the parts are great and installed fine on my tm mp5j, however the torque up gear set i had problems with. It seems that no matter how much shims I put when I close up the mechbox to test the fitment of the gears I cant seem to spin the gears. I tried with no shims as well and same result. I tried lubing the gears and bushings and it still wouldnt budge. But when I put the regular mauri gears they spin smoothly. Any suggestions?
