Oliver 80 surging

I have a late Oliver 80 that runs very well, but.. The governor has a nasty habit of surging. Before it is hot it wants to kill the engine and even at operating temp, it stumbles and "hunts". Had it on a dyno a while back and it would not settle down under load. The dyno operator at the tractor show said it was common for those models to do that and it was hard to get an accurate reading. I think there is quite a bit of slop in the linkage that has several moving parts near the carb. So, does anyone have any suggestions for smoothing out the running of that 4cyl Waukesha engine. It doesn't surge while idling, only when the gov. tries to kick in.
Thanks,
Jerry
 
Hi
I have had that trouble too. On the carb side I drilled out the holes in the linkage and put in bigger pins to take out some of the slack, and it helped. Then I readjusted the linkage under the cover on the mag side. Mine was a little lose if I remember right.
