I too have a mechanical stomp starter on my 39 Chevy truck, and my 29 Ford Model A. Along with electronic solenoid key/push button systems, came neutral safety switches, that prevented starting a vehicle while it is in gear. With a foot stomper, neutral and the emergency brake are a definite necessity. Four pedals, clutch, brake, gas, and starter, and only two feet. Too much for some folks to figure out. Some of my farm tractors with manual transmissions have a push button start that won't function unless the tractor is in neutral. My 72 Chevy Nova wouldn't start unless I had the clutch pedal pushed down to prevent it from starting in gear.
