My 2000 wgp autococker I got of ebay never worked. It never could "autocock". I was hoping I could just get it going out of the box and never screw with it. I don't know if it's because I screw in my co2 tank directly into the gun with no bottom line or the timing is just off. I shortened the cocking rod as much as it could go and unscrewed the back block till it was barely touching the body. I think the guy sold me a screwed gun and ran off with the money.....This is going to be really hard to fix when you have no previous knowledge of the gun.
