Hi guys, first time poster here so go easy
I'm trying to resurrect and restore a VM-68. The gun previously worked fine and was in a box inside my house for years. I stripped the gun down completely, replaced all the old o-rings, applied lubrication where needed, checked the valve position and cup seal. Everything looks great! Go and get a bottle filled, hook it up and no leaks great. Pull the trigger, blot slides forward and .... nothing. Not even a burp of gas.
I pulled everything back out and inspected the valve, cup seal, spring etc and everything looks fine. But, it still wont fire.....
Now, I would have expected that if there was something wrong with the valve it would be leaking baddly but it is not. I pulled the front section off with the CO2 line still attached and cracked open the tank and I'm defintiely getting gas flow into the valve.
So I'm pretty stuck here, any suggestions would be greatly appreciated.
