Hillbilly, 066 Fish Gill muffler mod

[Trigger-Time]

I have done this to 361 and 440/460 mufflers. Thought I would
try a 066. Yet to run it.

Still have the 066/660 bellow, like the dp cover has?

I have a couple of 066/660 DP covers.....It would be close. IMO the
bellow comes from drilling or removing the box inside the muffler. For
now I left the box alone. My 064 sounds better to me than my 066/660
saws.

That my friend is not Hillbilly. That is Mountain William. That is what mine is goimg to look like. I may send it to a hot rod friend that owes me a favor and have him louver it.

On second thought, a set of hardened steel dies and I'd be set for all my saws. Great work, thanks again.
