My close friend Dave Raubinger, now confined to a wheel chair with MS, made this tandem Cox .049 coupling system 40 years ago! He recently sent it to me to experiment with, so I decided to try to run it after all these years and see if it still would. It's unique with it's own oiling and gearing system. The .049 are still available today at http://www.coxengines.com I hope you enjoy seeing it really scream by the end of the video. Thanks for watching and subscribing.
