I said I was slow, but you can’t rush perfection. I had to cut about 3/16 off the stab and wing tube. The incidence on both stabilizer halves and one wing were off just a (wild) hare.
Cutting the cowl to fit over the muffler was a bit of a puzzle, but easily solved by shaving a bit off the bottom lip of the motor box and shaving a bit off the cowl ring at the top so the ring could pass over the prop shaft. There is no need to cut off muffler tips. I had already cut the tips off my Bison wraparound muffler for better engine performance. The cowl was cut just enough to fit over everything; I will be going back and widening everything for good engine cooling.
