Your answer actually tells me a lot, Mike.

I made a removeable section shaped roughly like a Central Hobbies or Dave Brown nose ring and I was working on a template for the fixed portion. The problem is that if you put the fixed portion far enough forward to not show in the air intakes you will need some standoffs or something to reach the removeable section. The whole thing wouldn't be sturdy enough IMHO.

I'll take the shape in your photo and see if I can cut clearance for my Webra's carb. I usually make a balsa mock-up before cutting out real wood.
