1. Checked the fit of the latest revision to the snorkel. This one finally looks perfect!
2. Used a Dremel flapwheel, plus coarse and fine sandpaper, to smooth out the snorkel and all three new clearance blisters. Attached the snorkel to the fuel servo.
3. Installed the #2 cylinder baffle as much as possible, and began marking the snorkel for trimming it. There really is no way to do this process in a few steps. It looks like this will be very iterative and repetitive: Mark the snorkel, remove it, cut it, re-install it, check it, mark it again, etc.
