I don't normally remove spring from governor arm but this time I did...I didn't mark it a week ago and can't see any wear on the holes.
Kohler CV14S.

The gov arm has three holes. Top is close to govenor shaft, bottom is furthest away.

If I put the spring in top hole, the RPM sounds too low. If I put spring in middle hole, RPM is a little high. I haven't run it with the deck yet. The choke linkage is adjustable once the RPM has been set.

I set the RPM by sound. It could be the 14hp is supposed to be quiet? I might have an old auto tach on a tune-up meter.
 
The governor sensitivity is adjusted by the position of the governor spring. Start with the middle hole. Move the spring towards the cross shaft to increase governor response sensitivity. Moving the spring away from the cross shaft decreases governor response. Engine RPM is not set by the governor spring.
 
That makes sense. But I am not sure how to set sensitivity. I am setting RPM by moving throttle cable.

This rider is a hydro. When I go from reverse to forwoard, the front wheels pop off the ground. I don't have the weight of the deck on it, so that might solve that issue.

I am going to take a closer look at the holes to see if I can find any wear.

Thanks.
 
Set throttle with the idle adjustment screw. That's the screw at the throttle plate quadrant where the governor rod hooks to the carb. Governor should have little effect on idle speed.
 
Had the same problem with a briggs engine, as to how to hook up the gov. spring. Went to youtube and typed in the engine # and a video came up showing all spring connections.
 
I used middle hole based on a 13 hp engine I saw in boneyard. Engine sounds ok. I can hear the governor working when pressing hydro pedal to go forward and reverse. I think the engine governor noise is more subtle because it is a 14 hp.

I didn't want to set the idle screw to adjust the working RPM because I want to be able to idle engine down.
