Response to Mine is low power too for no apparent reason!

Matty,

Sometimes soaking the seal expands it too much and doesn't allow it to gain speed. I'm assuming you've had it apart? Does the piston slide (in the receiver tube) with a gentle pressure?

If so, and all else is good, it is possible you have a bulge in the tube near the transfer port (could have been manufactured that way). This will result in a velocity decrease. Again, you need it disassembled and see what happens when you slide the piston down.

The bottom line is you need to strip it down to diagnose it.

Chuck
