AHS 1,546 #1 Posted September 22, 2019 I’m talking about old ones! Kohler K series. The newer ones I haven’t had a problem with...yet! The rusty muffler has a noise to it when you shake it...and it sounds like their is nothing there once the muffler is on it and it’s started! Has anyone cut into the bottom of it and stuffed some packing in there? I’m not sure what’s in the muffler. 2 Share this post Link to post Share on other sites
Pullstart 66,813 #2 Posted September 23, 2019 I briefly touched on using half of a Kohler muffler on Frank’s stack. It should be easy for you to cut the weld around the base of the muffler, pack it better then weld it back up. 1 Share this post Link to post Share on other sites

AHS 1,546 #4 Posted September 24, 2019 Ok! Question is “ where does the loudness come from?” Is the any packing in there? Share this post Link to post Share on other sites

These are low compression low HP engines... I used to work in one of the nation's top aftermarket car exhaust factories and packing was only used in performance or high end applications...

Burnerman 759 #6 Posted September 29, 2019 No packing. Just perforated pipe and 6 changes of direction if I’m counting correctly. They start getting loud when they leak anywhere. Any rust though at the top seam gets real loud. 2 Share this post Link to post Share on other sites

I will take a look there!👍 Share this post Link to post Share on other sites
