I ended up buying a 90-degree fitting to give me a little more clearance out of the carb. I used the small heat shield supplied with the kit, and made another one the same size. There was still a short section of fuel line that was only 3 inches or so away from the exhaust pipes. Since I just applied a bunch of heat shielding to the inside of the cowl, I took a couple strips of that (super thick tin foil with adhesive backing) and wrapped it around the lower part of the fuel line. Probably overkill, but oh well.
