I think another great modification would be to add an electric start, ive been thinking about rigging something up for a while know, i have a 7.2v ni-mh battery 2400mah and r/c car motor with lots of torque enough to turn the engine, i would charge the battery off the magneto, my problem is finding a way to mount the r/c motor so it would disengage from the pinion on the motor once its started because if it spun with the engine it would eventually burn out, if you have any idea get back to me.
