I will agree with that RamJet. I really dont consider any material dated. I dont know how many times I found a concept idea or practice that I though was new only to find it had been done many years ago and somhow lost or forgoten only to be brought back and utilized again. Besides if it wasent for jennings laying a foundation what would the rest of us have to build off of?
Combat, I have a neighbor who races a two cycle motocross motorcycle professionally. His bike has what I think is a remarkable design feature. It has an exhaust port valve that opens and closes with the engine RPM. Wow, the Achillle's heal of two stroke engines. Blowing fresh fuel air charge out the exhaust pipe at low RPMs. Ingenious I thought. Until I remembered Enyas with the exhaust flap that opened and closed the exhaust port in synch with the carb butterfly/barrel. What goes around comes around.
