I can get you an ammo can, almost any size you want (Camp Lejeune). Cut a hole in the box, bolt the box between two gaskets on the intake, now carb is inside box. Close the air tight lid. Pressurize the box. The bad part of doing it like this is the carb adjustments are inside the box.
If you want an ammo can, just say so.
