Roin, I have to disagree with you in a sense. actually if you listen to a John Deere they dont go putt-putt. That would be one piston firing at point zero and the other firing at 180. A complete revolution is of course 360 degrees. If you look at the mag or distributor, I think you will see one contact at zero and one contact at 270. The mag or distributor is geared to rotate half the speed as the crank which means that one revolution of the crank is compression stroke, the other is power stroke, therefore the two cylinders are both firing on the same revolution and firing depending how you look at it 0 and 270 or 90 and 270. This makes the sound more like Putt-tut....Putt-tut....Putt-tut.
