Ihave a used rcgf 45cc side carb that Iwould like to put a new muffler on.Last time Ilooked Ithink the bolt measurment was 43mm. Iheard the original rcgf muffler is cheap and will rattle apart right away. right now there is a b&b(bennett) that is in rough shape and was on it when Ibought the plane it was in. Is there an aftermarket or another engine companys that will fit? I haven't been able to find anything yet.
