I'm pretty sure Maverick was asking if your tank was LP or HP.

There are no stock number of shims. Can vary from 0 to 10 or so.

Did your gun all of the sudden stop shooting over 180?

Your name is "IlovemyA1", so I'd assume that to love it, it must have been shooting over 180 at some point.

Check your exhast valve stem. My marker started acting like that and then about 20 minutes later the valve stem came apart. If there is any signs of wear then replace and try again.

Had exact same problem, my lpr was 52psi, added 4 shims to get pressure to
58. If you don,t have a gauge you can still add a couple of shims to see if
you get your velocity where it needs to be.

I've had the same problem with mine the last couple of practices, however, I'm stuck at around 230-250 fps...
Running at the optimum settings, 57-58 psi, dwell around 6.5-7.5 etc....
Using a centerflag LP reg...

Will check the valve stem to see if it's causing trouble...
Anything in particular to look for?
