Trouble with my Tacamo AK

Bought for a steal, but I have a slight leak (internal) i took the gun apart and cleaned it up, i have replaced the infamous valve Cup seal and it has improved but is still a slight leak you can hear listening at trigger. Anyone else have a gun like this and experience this issue? I am thinking spring replacement or cup seal guide to see it makes a difference. I may also be a bad valve. I do notice that the cup seal guide is shaped different then replacement parts show, it is basically a PLUS sign shape and not round like the replacement part. Advice if you can give me some direction. Thanks

Come on Guys, you read the post but no one has ever had this issue, it is based off of a spyder gun so i know they are have same type issues, like the marker but the leak is a pain.

Couple things to try: use the original cup seal, but lube throughly before you put it back in.

put a couple drops of oil in the ASA, gas up the gun, cycle a few shots through.

Are you using CO2 or HPA? There is a chance that there isn't enough pressure coming from your tank to fully close the cup seal, hence causing a leak.

Still leaking, wonder if it could be the spring is shot, basically no holding enough pressure on the cup seal.

he means your reg's output might not be what the gun needs, and if you ran 3k psi through a gun im sure everything would fall apart/orings lose seals

Assuming the gun is a Spyder or VM clone, it could be one of the two O-rings around the valve, probably the rear one if you can hear gas leaking towards the grip frame.
