Raining today so I ask this. I have a 1966 2000 3 cylinder diesel with a little over 2000 hours on it. When the tractor warms, up the rpm's will surge about a hundred rpm for about two seconds and then settle back to original. Under load or at rest. Surge up, two seconds +-, down to original throttle setting. It does not do this regularly but intermittently.
At first I thought maybe the pump but it makes more sense to me the governor has a problem. Gov works good other than the rpm surge up and then down.
Any thoughts on this?
