shocker sport air leak

[invid]

having air leak probs on my shocker sport

soon as i open gas valve all the gas leaks out into barrel, the bolt will fire but at a low velocity and all that gas rushing out, if i remove the fire rod then i get a minor leak from selonoid base and my bolt still fires (again at a lower velocity)

all parts in this maker are in working order, i've cleaned, lubed and inspected everything including selonoids


helppp

wheres the cupseal?

 

[dr.strangelove]

A cup seal is what seals off the valve, the seal is broken by the hammer when a marker is fired. So, take out your valve, there should be a plunger-looking pin going through the center of it (looks like so when removed: ()------- ), and either replace the whole thing if the cup seal is part of the pin, or replace the rubber seal at the end if the cup seal is removeable from the pin (sorry, don't know what kind of valves old Shocker's use, or I'd have more sure answers).
