"Flapper closing noise" : well, it can't be totally eliminated. But it can be reduced. It has to do with the thickness of the felt and leather pad, and the spring tension. Thin felt/leather and stiff spring tension will result in a louder noise. Thicker felt/leather and lighter spring tension will lessen the noise. Another thing that can happen is, over time, the leather pad can get hard and dry, and this will result in the "noise". Hope that helps.
Thanks for the reply Jude, I was away from the computer for 4 days, that’s why I haven’t acknowledged until now. I’ll check in to that about the flappers. It may still come down to the way I play, not very smooth. I’ve never played anyone else's accordion so maybe that could tell me a lot about my own. I do appreciate your help.
