My thoughts on adjusting the striker is that CW increases the fps. Here's some of my chicken scratch tuning where I backed the striker all the way CCW then started turning it back in CW about a 1/4 turn at a time and recording the velocity. You can see that when back all the way CCW the striker did not have enough throw to hardly crack the valve open. After about 3 full rounds CW I was pretty much maxed out. Not wanting to over strike it I settled for the 3 rounds CW, anymore then I was probably wasting air.
