Good info y'all. Whatever the outcome on the muffler, it will be fun to try out. Mike I think I read an old msg on here where you said the 460 muffler fits the 440. Thanks for that.
On the 460 muffler - most of the used Sthil ones are in rough shape for the price in my opinion. There is an aftermarket muffler available new called "The duke's muffler with spark screen 440 460" on ebay for $27 shipped. I didn't know they had the deflector/baffle in them or I would have purchased it instead of a used 460 muffler for $29 bucks. * Confirmed the duke muffler does have the 460 baffle btw.
Checking squish when I get home, I picked up some solder on my lunch break. Maybe it will be too high to correct with a base gasket delete and I get to send it off to have the base cut. That would be kinda cool if not too expensive.
