Continued with FAB II. I had to make new clips to retain the air filter, the originals were 1", and made these 1 1/4". These clips the filter stays where you want when the FAB is mounted to the fuel servo. Mounted the FAB to the fuel servo to mark the cut out needed for the fuel mixture lever, using what I learned from the first effort to make sure the cut out is exactly what is needed, and no more.
