It's most likely a micro switch, could have some crud in it causing it to stick, or just going bad. Easy enough to check with a volt meter, but something has to let current through to the starter generator for it to just turn over and keep going. If it's actually firing, then yes your still getting fuel and could possibly be an open butter fly, just unhook at the carb while it's idling and see if it closes and shuts off.
