Old Tech question

Found a stash of old 8 tracks.

So for kicks I drug out an old record and 8track player from a relative’s garage.

So when I put on an 8track, it won’t play. If I pull back on the 8 track a little and hold on to it, it plays fine. Let go and it stops. Any ideas?

Then I put on a record, and everything is fine, but no sound in the left speaker. Both speakers work fine when I get the 8track to play, but not the record.

Any old timers know what’s going on other than that it’s just broke?
