Remote air duct for Kohler K161 on a 2.5RM gen?

Has anyone seen a remote engine cooling air duct for a Kohler K161 ( K181 is the same) engine? It is powering a backup generator 2.5 RM22. ~ 1967 build, 2.5 KW

The plan is to mount the generator in a concrete block room (8' X 8') under the front porch and run the exhaust and hot engine cooling air through the wall.

I've seen larger engined International Cub Cadet lawn tractors with a air duct system but don't have one handy to check. I can build some tin work, but it is usually easier to purchase a existing part rather than fab one up.

The gen system will have a CO detector in the next room and a old race car remote trigger fire surpression system :+)

Thanks Harold

I recently acquired this type of generator and have the front cover you are looking for. Would you like a pix of it or I could draw it and send you a plan of its construction.
