Abstract: This wiring circuit allows for the use of an electric starting motor to revolve the model engine up to its normal operating R.P.M. range before the glo plug is ignited. This method provides combustion within the engine cylinder at a time when the propeller or flywheel has built up sufficient momentum to provide high enough piston speed to carry over the top dead center point at which combustion occurs, and eliminates the probability of the piston being driven backward causing backfiring or kickback.
