Hello MCB, got a question about when WGP changed their springing for ya'.

I know the older pre-98' models didn't come with a HPR on them, and I've seen many that ran HP air or Co2 directly into the gun.

Now I shoot a 98' model, this was the year they started to use the HPR as standard equipment and apparently they enlarged the valve chamber along with it.

Now, what I'm trying to acheive is just by running a piece of macro into a 1/8" NPT to ASA adapter into the vert ASA and just run my Cocker un-regged, but I'm not sure if the 98' models needed re-springing to attatin the right velocity and efficency by running 850psi directly into the gun. I remember reading somewhere the pre-2K models ran at like 400psi or something.

So, will my gun need a re-springing to acheive a low enough velcoty and maximum consistency, or could I just do what I want to do without re-springing it and still be able to shoot below 280 FPS (field's limit) and get good efficency?

Thanks.

Also, what is holding the plug on the bottom of my front block in? Whatever it is it's doing a damn good job of it. Here's a pic of what it is, I suspect JB weld, but I dunno.

The changeover from Sheridan springs to Nelson style springs was in 1997 I believe. I'd imagine a 1998 Cocker could still run off unregged CO2 though since it's using the old style valve with the smaller diameter cup seal. The easy thing to do would be just to try it. Worse case scenario you'll need to buy a spring kit and swap valve springs.

The front block plug is probably held in with loc-tite and/or old age. Try warming it up by running boiling water over it for a minute then wrenching on it.

Alright, I'll try and make it down to the field this weekend and see what I can do, I'm having a strong gut feeling I'm gonna need to replace the valve spring with a heavy one though, thanks for the help.

I converted my Cocker to Nelson springing, but it still uses the stock valve spring - it runs at around 400 psi very happily. That's with the stock old-style valve.

Now, I don't shoot very fast, so it's probably fine like that - with something like an E-blade on it, I'd probably move to a much higher flowing valve.

I'm thinking you might very well need to swap out some springs.

WGP started the standard reg in 96. 98 they changed to a threaded IVG and larger valve chambers. Sorry, just FYI.

1998 -

Top Timing hole added
Screw IVG introduced (previously was a smooth fitting held in by beavertail screw.
WGP inline regulator standard.
Front of sight rail sloped
rear of sight rail rounded.
bottom edge of body rounded - excluding asa
Nelson spring-compatible hammer.
Enlarged valve chamber.

Got that info from here.

All true, but the standard regulator ball detent and cut back block started with the 96.

You may actually find that you need to raise the hammer spring.

Yeah, that's the one I'd be worried about because too low of a velocity would be more of a concern. If you run unregged you have 850psi holding the valve closed but the hammer spring was designed for a valve being held closed with 400psi or below. The spring will not have enough oomph(technical term) to strike the valve hard enough for a full strength shot. A Freeflow Tungsten hammer would help but I think you'd still need a heavier spring to strike the valve hard enough to overcome the unregged pressures.

[Milky Spore]

What about a heavier valve spring for low dwell, a heavy hammer and medium strength hammer spring?

It's probably good that I'm doing this anyways, my Cocker farts if you just pull the trigger enough to where it will only fire but not re-cock.
