Paintball

I hadn't played with my viking in a while. I got it out last weekend to show it off to some people. It wouldn't chrono over 250. I figured it must be a weak battery. We shot it without any problem, just wouldn't chrono any higher.
So, i've gone through just about everything. New battery, checked dwell (at 12), reset lpr (approx. 60), swapped hpr regs with a marker that i know was shooting close to 300, i even swapped the asa. After all that, it still wouldn't go over 250. Then at some point it just stopped shooting. I hear the solenoid click, but the ram isn't responding. Yet, it will shoot maybe once if it sits for a bit. Could there be a clog in a air passage? I'm stumped at this point.

To recap:

Settings: dwell12 tadao m5 board
lpr 60
checked regs
new battery
robtown valve

And when did the scm3 become standard on vikings? I have an 04 immortal and it has the 4 hole lpr.
