Question about Sport & Outdoor - Others
I have a crosman Pumpmaster 760 that I've own for the last 33 years. It won't pump up pressure anymore. I've had it apart and the only thing I can figure out is it must be in the valve tube, but I can't seem to remove the valve to inspect it. I don't want to force it and break anything because I want to keep it as original as possible. It has never and I mean NEVER had any repairs done on it ! How do I remove the valve assembly from the valve tube?
Hi I had the same problem and I fixed it by just simply pumping the gun at a faster rate. For some reason when I pumped it slowly air would leak out and no pressure would build up similar to your problem, but when I started to pump it rapidly pressure would build up. Though this little fix works I might just exchange mine because I don't think the gun should have this problem.
