Well all I can say is we will see what happens. I am seriously thinking about making the switch to one for my trolling motor. Sometimes we don't like change, do we? If it was up to you, we would only have two stroke motors, you would be honing valve and valve seats with a suction cup stick on the valve and using valve grinding grit and honing the valve and seat one at a time. Actually, I did that on a 59 Nash metropolitan my first car. Had a great uncle that was an old-time mechanic that instructed me on how to do that. We would all be driving old pickup trucks and ford mavericks. No phone no lights no motor car not a single luxury like Robinson Caruso as primitive as can be!
