I bought a Showtime 50 last weekend and started putting it together. I have an O.S. 46 AX to put in the plane. Don't start the same old rhetoric on you need a bigger engine. The 46 Ax is plenty for this plane. The problem is mounting the muffler. The plane was obviously built around an evolutino engine. When I got the engine mounted the muffler doesn't clear the cut out on the fuse. I loosened the back half of the muffler to see how far I am from getting the muffler in there. This is where I need ideas. Muffler extention , different muffler or make a few cuts to the fuse???

What to do what to do? Here are a couple pix of the situation.........
