I just bought a 02 wgp autococker. It did well the first time I played with it but it has a problem. Sometimes it will not fire. The bolt will cock back and load a paintball but it will not fire it out. Sometimes I will get up to 4 or 5 paintballs in my barrell before it fires. The cocking rod is tight and I am fully depressing the trigger. The problem does not happen every time I fire it (approxitally once every 5 or 10 shots). DOES ANYONE KNOW WHAT IS WRONG WITH IT????
sounds to me like your cocking rod is not adjusted correctly, or you lug is in too far. The bolt and hammer are coming back, but your hammer lug is not catching the sear. So when you pull the trigger the bolt cycles but the hammer is not released. that would allow another ball to be loaded, then eventually the lug catches the sear and fires and you have 8 balls in the barrel that begin to ooozzz out the end.
there should be a small allen screw in the end of your cocking rod. you can loosen that and turn the head of the in a couple turns. (that will shorten you cocking rod allowing the backblock to correctly cock the hammer)
If its the hammer lug that is too short then you just need to take the bolt out and insert a 1/8th allen wrench into the top of the body and add a 1/4 to 1/2 turn down on the hammer lug.
my bet is on the cocking rod length though. ussually with a short lug you will get a "skipping" issue where it shoots multiple times in a row from one trigger pull.
there was a guy at my field with the same problem... i forgot how they fixed it. but if you do what those guys said ^^^ and it still doesnt fix it you can try turning up your lpr. but my guess is the cocking rod is too far out or sear is too low/hammer lug is too high
I was just recalling my first experience with my eblade. I cranked the grip screw in too tight and it pinches the sear not alowing it to move (holding the hammer in place.) It would also cause that issue. Just as Paintthebluecat described, lub too low/sear to high. I could be slipping off the sear once in a while to actually fire. My first thought is still the cocking rod depth then a lug adjustment. I would suggest he just take it to a shop and have it timed. or go threw the learning process of timing it correctly himself.
after the marker cocks, if you can pull the cocking rod back by hand and feel it catch on the sear, you need to adjust your cocking rod length. If you hold the trigger in, and it will not move you lug may be too low. Also this can all be done with no air.
