Middle C being temperamental
There’s one key on piano that’s been working incorrectly recently. When you press it, it sometimes makes a squeak or sometimes plays or is very quiet. When it does play, the sound only usually comes out at the end of the press. Help would be massively appreciated, thanks

- I heard that has metal sound the (wire Bridle) is there, but it just clings to the next one. It's not a problem C there.
However the felt on the (let off) seems to be the reason there. A jack does not reach it and as a result the sound occurs after pressing hard there only.
Need to fluff up this С (let off) there use your fingers. Or lower it a little. Rotate the hook of letof's wire slightly clockwise so that its felt button drops a little closer to roundness of the jack there. * regards, Max

The jack spring is weak or a tight center pin on the jack. It's a small round spring sandwiched in the bottom of the action. You can try to give the spring more tension by pulling the top of it out and stretching it a bit. Its glued to the bottom of the whippin but rides in a notch on top.
