In the case of a rough running engine due to the air filter getting clogged and restricting the air flow there is an alternate air door on the side of the snorkel. This door can be opened to allow unfiltered air to supply the fuel injection system so the engine continues to operate normally. I had run the cable in the cockpit some time ago and fabricated the door hole per the plans. Today I measure and cut the cable and attached it to the door. I also secured the cable with adell clamps to the oil return line from the forward cylinder head. 
It operates smoothly when opening and is not intended to be closed again in the air as the cable has to much slack to push it closed without bending. The idea is to get you back in the ground safely they return the door to the closed position after you remedy the cause of the clogged filter.
