John--scroll over, a LARGE closeup is located to the right of the first photo. Shows the substantial cowl cutting for the muffler.

Thanks Chuck--Before I ran the engine I took up a lot of the slack you see in the photo. I just sort of quick installed the cowl for the photos. The plug wire now does not rub on the cowl and in addition, I wrapped numerous layers of electric tape where it may contact the underside of the cowl.
