If you want to quiet your gas engines, Go to New DLE 20 thread, page 44 post 1081, and 1097.
I discribed how I quieted my 20CC, and 30CC Gas engines. There is also pictures showing how to do it.
I am still using this method today and everybody says than a pitts muffler. By the way I see no lost of power
or RPM.
