I just don't get it... I've rebuilt this thing all the way through and can't seem to get it to shoot above 200fps.

I've messed with all the settings, set it to default, made all adjustments on the LPR and HPR. Just about to give up on this thing!!!!

Think it might be the solenoid?

Any help would be great.

Replaced the rear ram o'ring? what's your dwell at? have you checked for leaks/kinked hose on the rear LP side?
