By the way the standard chrono is .20g bb's for most North American fps limit measurements. 100m/s is about 350fps, but with an m120 spring expect about 400 fps on .20g bb's. Try to re-do the chrono on .20g bb's if possible.
Usually loctiting the piston head isn't an issue, but it doesn't hurt to do it anyway.
You should try to use the bevel-pinion method to shim for the best performance.
If you could, please post some pictures so that we can see exactly where the failure occurred and we could possibly give some input on how to prevent it.

hehe yeah i know, I had only chronoed it with my .28 at a game, 2 hours before it all broke down. but i have ordered a chrono that will arrive any day now.
yeah, will shim it to the motor. one more thing btw, one screw hole for the handle to the geabox was stripped when i got the gun, can this cause alot of problems?
will put up picks in a couple of minutes
