a spring loaded contact lifts off the commutator ring as the engine reaches a certain rpm. The tension of the spring is adjustable to raise or lower running speed, although i have never tried to run anything off it, so not sure how effective adjustment is.
A nice motor
lovely engine ,how does the hit and miss operate on this engine .?
