Some of the Diesel engines I drove had a spring-loaded cap like a big oil cup on the intake manifold so we could give the engine a dose of starting fluid on a cold start. Something like that would be easy to add to an air cleaner cover for a shot of gasoline from a ketchup squeeze bottle when a hangar queen gets started after a long sleep.
