Thanks for the generous reply! Obviously, my reed valves must be working well!
I had to revisit some of my collection, I suppose my Johnson series ‘A’ accomplishes porting with the crankshaft acting as a ‘blowback’ valve?
My fleetwin does have the original coils, it would stand to reason if they are known to go bad, I should replace them. It shure runs smooth on one cylinder.
Anyone know a part number for replacement coils?
