I'm on the final stages of my Byron CAP 21 with a converted 45cc Homelite. My carb is about 3/4 inch from the side of the cowl. My velocity stack is twice that length. Instead of cutting a big ugly hole in the cowl, can I just leave the stack off? If I have to put it on, would it hurt to cut it down so it fits inside? Which direction should it face? Angled part forward or backward? Thanks guys.
