Avo 7 Mk2 cutout issues

[BusyBee]

I had that problem on my '8'. It steadily got worse over time. On dismantling I found that part of the mount was broken which made the works insecure on one side (If I remember rightly the spring was putting a one sided force on things so the catch was touchy). A touch of superglue fixed the mount. I did not expect it to last long but luckily has lasted a good number of years now.
