I need a seal rebuild. I lose air right away when pumping. There also the cup on the end that was dried out. Does that even come off or is it a while part. Looks like it's pressed in. The only numbers I found were 88 on the plug.
Hi all, I have a older power master 760 I'm looking for a serial number, but don't see one anywhere. Please help. It was my grandpa's back in the day, I shot it a lot when I was a kid, I want to find parts and can't get anywhere.
