well i think the pictures says it all, i think my only two options is to either take the dremel tool and cut an area around the muffler to clear the fuse so the vibration is not so bad from the engine plus the heat on the fuse there. or take engine mount off fill the hole with epoxy or balsa filler and ca then redrill where it will be centered in the area for the muffler to fit. i checked the manual and the template was done right and the holes are where they are suppose to be per the template the manual says a os 91 fx is the highest to go for a two stroke and pictures use a os 61 fx so the muffler clears fine with a 61 fx. but give me some input on what you think thanks mike lansford
