Walther CP3 problems

[mattw975]

Hi guys,

I am having issues with a Walther CP3 that isn't behaving itself.

I have sealed a few CP1 & 2's with no problems but this has me beat ? Moreso because of its very simple design.

The valve looks fine & I have replaced the O Rings with ones sourced from Protek UK.

When I then try to shoot it, I either get no gas fired, a few shots that peter out or the whole CO2 tank dumps out the barrel. I have stripped the gun twice now after the gas dumps & the green polyurethane seal has puckered inwards towards the valve.

My thoughts of possible causes are:

1. Sub standard seals ?

2. Valve worn ?

3. Valve spring worn ?

Any advice or guidance you can give would be greatly appreciated,

Many thanks,

Matt W :)

Check the valve stem if it is not conical in back that’s your problem we had a few cp3 with this issue once we installed conical stems issue solved

The oval one is the good one
