muffler bar problem

[Clyde Hollinger]

Friends,

The last piano I tuned today was a 1998 Samick vertical, model JS-112.
If I adjusted the muffler bar so the hammers would just hit the felt
when it was engaged, the hammers would catch on the felt when the bar
was disengaged.  Is there any way to make this thing work properly?

Regards,
