Did the cowl last night. a lot of aligning and taking the engine on and off a number of times. I'm still liking that mount. The instructions called for sanding it all down with the engine installed but I did not want to do that so I marked the location of the spinner on the ply spacer ring with a pencil and sanded it down with the engine off. This went pretty fast with 80 grit sandpaper.

I know I dorked up the holes for the fuel lines. The drill bit slipped. I'll fix that with covering and white silicone later. You'll never see how ugly it looks.
