I know that there are thousands of questions about troubleshooting them. I do what they tell me to do. I turn the adjustment screw in and fire 4 or 5 times until the trigger pull is hard. So I know that its right. So i slowly start turning it out. But i cant get it to "pop". That piston doesnt push out some times. Could there be a problem with that? Maybe I need to lube it perhapse. I just dont know, if we had a shop in the area I would bring it to them but we dont. I have spent weeks looking on line trying to figure it out.
