So went and bought a namura piston kit for my blaster. My bore was still within spec and did not have to be bored out so I asked for just a standard bore piston. I went home and started to install the piston. Well I got the piston to go halfway in the cylinder and it will not go any farther. I checked the box of the piston and it says .020 on it. So is this piston too big?? I have tried a block of wood and a hammer and I cannot for the life of me get the cylinder to slide down over the rest of the piston. HELP!!! Trails just opened up where I am and I want to ride!
