I worked hard to trim the cowl to get an inlet height of 2 3/4 inch. I got the height set, and I fitted the cowling a bit low at the front, as most builders report that the engine sags a bit after the aircraft flys a few hours and the rubber engine mount bushings take a set. I hope that engine sag happens fairly quickly, as I don't have much clearance between the top of the valve cover on the front left cylinder and the cowling.

This week I finished trimming the lower cowl at the firewall, then drilled the bottom and sides of the lower cowl to the hinges. Then I trimmed the edges at the horizontal line where the top and bottom cowl meet. Then I drilled the cowl to the two pieces of hinge that go at at that horizontal split. I also cut out the opening for the oil filler door.
