HW100 Thoughts on Tuning and Tweeking

[smack6969]

I have a used HW100 in .22.  I purchased it used with a slow leak, but shootable.  Now the rifle will not hold air above 1000 psi.  It leaks from a hole in the bottom of the machined block which houses the valve.  I have a set of "o" rings.

So, when I disassemble this rifle to replace the "o" rings, is there any major do's or don'ts I should know about?

Anything I should tweek in order to improve the rifle?

Thanks
