I actually thought of using a K&N breather filter as an air filter.

But since the filter is on the side, and the carb is the one part I think ruins the look, a walbro clone sticking out a ways, I couldn’t find anything that was quite what I wanted.

My goals for an air box are, functional, a flat, pancake design, and just about big enough in diameter to hide the carb.

Then I made cinnamon rolls. I actually made two batches, having burnt the first one, lol. Turns out, the pop n fresh style rolls come with a plastic tub of icing inside one end of the tube. The little tub of icing has an aluminum cover, not unlike the end of the tube, except a little smaller, and the rolled edge isn’t crimped.  It’s a perfect little tray, or base or lid for an air box.

One lid got drilled to match the intake flange and carb inlet. The other got just two screw holes. A 1/2” wide band of .015” brass forms the sides of the can. Z bent and soldered into a ring that drops in between the two discs. A slot 1/4”x1” in the bottom aspect of the band is the air inlet. A cut down blue scotch-brite scrubber makes a dandy element.

Best of all, it hides that hideous carburetor.😁
