Bisquette advance button

[afreitag]

The advance button has been sticking on my OBS. I took the button out and cleaned it and it pushed in and popped back out just fine. I put it back in the generator and its sticking again. Took it out again and it works fine. It only sticks when its in the generator. How can I fix this??

Yep, hole in tin is most likely a touch too small, and pinching the button.
Remove button, and give the hole a couple strokes with a fine--WARNING, it doesn't take much. 
Repeat if necessary.

It did the same thing for me. I pushed in about halfway and it worked fine.
