We have 2 of these engines that are giving me a fit. Both engines were totally overhauled within the last 6 years with some use since, but definitely not worn out. The one in the harvester started acting up 1st the end of last season. I rebuilt the carb twice, installed new manifold gaskets, and new coil with no change. The one in the Hahn hiboy has had the same treatment,except for the manifold gaskets changed. What happens is when the engines are cold, they work fine. Once any warmth has occurred, and especially in hot summer time Temps, they will start surging the governor and fall flat on there face until it is set back to an idle position on the throttle control. Both are getting plenty of fresh gas at the carb and plenty of fire at the plugs. Both engines have had electronic ignition installed for years. I'm stumped as to why they will both run fine at idle or half wide open but not at 2 to 2400 rpm consistently. Any ideas ?

The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
