They do sort of sound like a hit n miss engine. It's a fact of life with a 2 cylinder 4 stroke engine. With any 4 stroke engine, it takes 2 complete rotations of the engine for a complete cycle, so on your engine the first cylinder fires and 180 degrees later the second cylinder fires, then it coasts for 540 degrees until the first cylinder fires again and the process repeats so it's putt-putt---------putt-putt--------.

The reason you notice it on the JD's more than other 2 cylinder engines is that they turn so much slower than others
