I hate taking airguns apart but finally decided to take the plunge and have this Vortek kit to install in my 177 HW77.
I comes with two thick washers (spacers) that are used to vary the power but I have no idea how to use them. The blurb says it can do around 13 - 17 ft lb and I would like to be at the lower end / middle of that. I think they slide over the piston to go between the top hat and top of the cylinder (correct...?). Do I use 1, 2, none...?
I have sent the same question to AGS and Vortek (might phone them before I start) but I would guess someone here knows the answer?

I love taking them apart, it's putting them back together that's a pain. :)

I think it is suggested you put it back together with the new kit and run it through a chronograph test, then decide.

I know the HW's can be a pain to work on without a good spring compressor.

I really don't like the bit where you need to take a hammer to it to undo the cap and then again to do it up - and get the dovetail perfectly straight...
As for testing things out and going through this process over and over, I don't think so!
Anyway, if anyone has the same question for future reference from Vortek:
"Washers go in front of kit -over center rod into the piston then the kit-.
No washers should shoot around 13.5-14.4 ft/lbs.
Each washer approx. 1/4-1/2 ft/lb increase."
They also took into account it being 177 with that reply so I guess the claim of the kit being adjustable across such a wide range really takes into account both calibres so isn't strictly representative of the possibilities.
I might try one washer, maybe none. Especially if the difference means setting up my car jack compressor but I expect either way I will need to rig it up again.
Good, fast and useful reply from them though.
