Anyone familiar with Marlin 39A lever rifles? I have one where the carrier/rocker doesn't always came up to lift the next case in position, and can't figure out exactly why. I'm assuming it just cams with the finger lever, just not sure.
This is the position its supposed to be in with the lever fully lowered...
...except, it doesn't do this every time. About half the time, it seems to make it only to the middle position.
Suggestions? This is a pretty old one, likely pre 60's (or even earlier).
