Yes, the old battery ignition Knucklebuster Eltos will start and run backwards if you learn the technique. I learned that the hard way years back when I started a 1928 Elto Speedster with the timing not quite right and it backed into the dock, bending up the prop.
Here is my 1928 Elto Quad, running last fall. Fun motors! They start with a quick flip of the flywheel knob and away you go!
