Enclosing your air compressor is no example. A convection-air-cooled 10 HP
gasoline engine puts out huge amounts of waste heat. Mere air exchange is
not the issue. If you enclose free convection, you raise the ambient
temperature around the fuel tank dangerously, where it can and will boil.
You can hardly put them up against a wall.

As I have no experience in this particular application of air-cooled
IC engines, I'll bow to your expertise.

I thought the intake air would supplement the convection enough to
handle it. Don't the air-cooled types use fans, too, though no
radiators? Aim the fan output at one side to increase draw on the
other.

Then again, most generators I've seen have radiators and are liquid,
not air, cooled. shrug
