Both guns I stripped down the trigger / hammer rail assembly and hand cleaned each part and reassembled carefully. The Valve knocker spring COULD be a problem but It looks fine physically and looks the way it is supposed to according to the exploded diagram. That spring is probably related, but for now it seems it may simply be the output valves on both of my mags : I have cleaned them, soaked them in silicon oil over night, lubricated them as effectively as possible before putting them back into the mags, but still neither mag will fire off. Maybe a recorded video could help?

Part 40 isn't doing its thing right or part 38 is somehow failing already even though both guns only have a hundred or so rounds through them at most.
Problems with these guns started when sand / dirt got within a mile of these things... just dust in the air and a bit of kicked up sand ended these cheap GBB's careers. I'm on the road to trying brand new output valves (CNC Machined Stainless Steel) as that MIGHT be the problem but i feel like i should be getting some gas release here and there as I now have the hammer spring up to approx 150% through shimming and when i i test the knocker on my finger it hits with good force. I guess part 40 (knocker spring) isn't lining the knocker up right with the output valve or something.
It really feels like it is NOT a problem from dirt or anything, just a lousy design with poor tolerances. I would love to fix it though to get these operational and back in the arsenal.
Any slick ideas or a gun doctor in Scarborough/Toronto with some time on his /her hands would be appreciated. These ARE cheap beginner crap pistols, and have left me permanently disappointed with the quality of WE/WETTI Airsoft, especially since I own a KWA ATP now which is miles better, and my roomate has had three WE/WETTI guns fall to peices on him. that being said, even though they don't belong on the market because they are a waste of money they are built so poorly, I wouldn't mind fixing these pistols so my friends have something to use if they come out for a game.
Any help massively appreciated, im sick of cleaning these and putting these back together and getting no help from WE/WETTI. Those guys seriously make some sh*tty equipment.
