"Funk" on the Muffler eewwwwwww
I recently came across a Magnum .91 Four Stroke.. it's used but in good shape.. I cleaned it good and fired it up this evening.. (put it on my Miss America, can't wait to see how it flies) seems to run good but a little loud to tune at home so I"ll have to wait until I"m at the field. Anyway... there's this dark red almost black FUNK all over the muffler and head pipe... this stuff is THICK.. I dremeled away for what seemed like forever and it WILL NOT come off... this stuff is unbelieveable.. what is it? just old fuel? is there any way to get it off so the muffler will be shiny again?
