Robin EH17-2D - Stopping with Fuel Cock

STOPPING ENGINE WITH THE FUEL COCK
Close the fuel cock and wait for a while until the engine stops.
Avoid to let the fuel remain in the carburetor over long periods, or the passages of
the carburetor may become clogged with impurities, and malfunctions may result.
If your engine has an electric starter, set the key switch to the "O" (STOP) position
after stopping the engine.
