1. With the Pott (sic) - No.33 off, screw in the Valve Cap No.34 till it bottoms in the End Plug No.38.
2. Unscrew it by 3 full turns.
3. Screw in the Pot No.33 all the way till it bottoms on to the Valve Cap No.34 (with the Latching Nut No.89 loose). Then, unscrew the Pot No.33 by 1/2 a turn and then lock off in that position using the Latching Nut No.89.

Now, these settings may not be exactly how it was from the factory but this setting works in terms of best shot count for UK legal sub-12 ft.lbs if the following steps are followed -

To set the power, start with the M3 x 12 No.8 Screw (venturi) all the way out. Then, set the max. power over a full shot string at 11.5 ft.lbs by loosening / tightening the Main Spring Adjustment Screw No.22 only. Then, bring the power down to 11.3 ft.lbs by winding in the M3 c 12 No.8 screw. This last step of winding the power down using the venturi screw is essential in order to get consistency.

If you get stuck, give me a ring. I will PM you my number if you need it :)


Are these settings good for a .22 and .177 or are they different?

I have had this work for .177 - sorry, not tweaked a .22 yet.
.22s are supposed to be more efficient i.e. use less air/shot at a given power setting. I am not sure if this might affect the settings themselves.
