Is there a muffler to replace the stock spring type muffler on the Mac 28 cc motors.

thanks

I bought a couple mufflers from CH ignition at one time. They had a method of drilling down through the fins from the top and inserting aluminum rods that were tapped in the center for the muffler bolts.

I just reshapped the original spring retainer strap and hold them on like the original muffler was.

The Mac 32 blower had a bolt on muffler.

what I did with mine was take out the tiny 1/4" outlet, welded that shut (was harder than you'd think with an arc welder... but it worked eventually) then took some 1/2" tube and put that out where I wanted it to exit then welded it in place and sealed it with JB weld. there's also a baffle in there that you can cut the center out of

the trick is to cut off part of the crimp that holds the muffler together, just cut off one end then slide the muffler apart (it'll require some assistance with a hammer), when you're done just slide it together again and weld shut

I also did a couple like was mentioned above but I brazed them back together.

yeah, do whatever works, I have a nice arc welder and have some 1/16" rod, put it on a low amperage setting in DC and went at it... if I had a brazing setup I might have done that...
