Morning

I have an old Daisy 200 my dad bought when he was a kid. It leaks Co2, and is missing a spring. I know a lot of people think their junk and not worth fixing, but I would like to try to get it working so maybe someday I could give it to my son. Any help would be appreciated.

This is from my notes:

I use a narrow piece of clear plastic cut from a grocery store food container (baked goods, vegetables, etc.) to use as a kind of shoe horn. The idea is to insert the plastic from the rear so the spring that is above the shuttle or elevator (which ever you want to call it) will ride on the plastic strip as the valve body/barrel assembly is slid out of the gun. Also, be sure the spring-loaded BB follower isn't hanging up. It's kind of tricky to get everything situated. but when things are right, it will come apart w/o any undue force. Usually, a gun that has been carelessly disassembled will have a ruined elevator spring, and it will need to be replaced to get the gun to work.
