Is this the screw for lp 400 velocity change?

Need to increase velocity for my gun. Is this the crew I need to rotate clockwise? How many turns?

Yep....but don’t forget to loosen the grub screw on the side first. Try 1/4 turn at a time clockwise.

thanks for reply. I am not really aware of the grub screw. Which one is it in the pic below? 1 or 2 ? I have to turn them anti clock wise then retighten them after rototation velocity screw . right?

If my memory serves me right there is a grub screw either side that has to be eased allowing the pressure adjustment to be turned.

You can check by looking to see if either one or both are in line with the adjustment screw. If both are on the same plane then release both otherwise choose the one that is correctly aligned.

I no longer have the LP400 to check.
