I just got my '88, 322 running on all three cylinders again after a LONG period of time trying to figure out what was wrong. During that time I spoke with numerous technicians at local John Deere dealerships and they all THOUGHT it was the ignition module after I explained the results of the troubleshooting tasks I'd performed. I emphasize "THOUGHT" because none of them had much of a history with the Yanmar engine and, that wasn't the problem.
My question to all the current and past owners of a 322 is, how many of you had to replace the ignition module and what was the hour meter reading when it went bad? Thanks in advance for your response.
