Did some searching and googling, but haven't found any answers I was looking for.

I bought some new King Arms 6mm oilless bushings, and they fit nice and tight into my mechbox. However, when placing the gears into the bushing it was a bit tight, and the gears didn't spin as smoothly as my nylon bushings. But they moved, so I figured it was good enough.

After assembling the bushings I installed my Bushings, Guarder SP 120 spring and Guarder spring guide (the awesomely heavy one), I gave my gun a test run. Nothing spun at all.

I figured the spring was too strong for the motor, so I downgraded it back to my stock spring. It shot a few times, and then it got stuck on the last tooth on the piston. Thats when I started to worry about the new bushings I bought

So I went back to my stock bushings and stock spring, and it started shooting flawlessly again.

So now I'm thinking, maybe the new bushings were too tight, and yes, I've greased them properly. I've read some advice where people told me to drill the bushings, but before I do that is there a better approach?
