Aero Injector: - Kerry at Sonex said to reverse the screw (come in from the other side) so the cable would be pushed AWAY from the mixture arm. I had to tap the end of the swivel nut, since it the screw would not go in from that side; the hole was slightly too small. After tapping, the solution worked fine.
Cowl: - Feeling under the weather, so just cut the hole in the bottom corner for the gear leg. Made it bigger than it needed to be. I can always throw in a fiberglass patch later if I think it's needed.
- Cowl does not fit flush vertically to the back of the prop hub spacer. The bottom of the spacer is a good 1/2" beyond the cowl. Even if I shimmed the top two engine mount bolts (to tip the engine downward), it would never make up that much distance. I'll do some more fitting before I decide what to do, but I may have to cut the bottom of the cowl so I can pull the front flange to the hub, and then patch the resulting gap with fiberglass.
At prop hub
Roughly at fuselage (lots of fitting and cutting to go).
Gear out the bottom. Hole larger than it needed to be.
