Just curious if anyone might have a muffler for a YS61SF? Macs, I see, sells a muffler(#6700) and an adapter(#6808). I thought, maybe, in someone's pile of used stuff there might be a muffler hiding that used to be on the YS61SF. It would be going to a new home and brand new in box 61SF. I don't want to use a "strap on" if I can avoid it.
