Hey folks new here. Years ago my dad was given a Secret Shot II as a gag gift. Me and a kid I was babysitting were playing around and I think it got over pumped because now it wont fire. This is now, many years later, I found it and decided I want to fix it but I have no idea where to start. I know literally nothing about this stuff but I just want it to work.
So yeah, Secret Shot II. Totally stock. Will not hold any air pressure to be able to fire. Need to know how to fix this and I am totally a layman here. I know nothing about the inner workings of this thing.
