I started with 1 1/2 hours of cleaning the shop including mopping the floor.
In the process, I found that I had not fit the air filter retainer. I worked quickly to adjust the fit. I decided to add an extra retaining screw in the lower right of the photo. That required that I add a nutplate to the snorkel. In doing that, I decided to clean up the fiberglass work a bit. I got out the dremmel sander and did a lot of smoothing. I found that I had not riveted the alternate air system in place before fiberglassing it in. I added 5 rivets.
