Autostart woodruff key with tang

Add electric start to your model! No more bad backs or scrabbling about on the ground! No more flipping a prop! Not just the bling value safer starting without risk of injury. Simply assign it to a switch and start your motor with the push of a butting/flip of a switch. Drive gear incorporates a one way bearing so power is not transferred back to the motor. The unit can be retro fitted to your existing engine!
