shadow462 check your on/off pin, on/off o'rings, clean and oil your valve.

Strider stay with the 2 carrier and try less shims. Are you chrono'ing down in the 250's with the cut spring? If not then goto the short spring.

obsolete898 All your problems might be solved just by going with a larger carrier(the largest that doesnt leak). It will require less pressure to move the bolt and less pressure means slower bolt speed(a tighter carrier does NOT slow the bolt down more). Also make sure cut side of spring is on the bolt.
I'll try that but I think it leaks. We'll see. Thanx a bunch.
