Kohler sticky governor??

[BLES]

On the larger Kohler Command Pro CH36/38/40 style, I've seen one and had a call about 2 others where the governor arm is sticky. Flick the lever loose before start-up and they usually run ok, but especially after stopping they stick again. Doesn't seem to be in the linkage to the carb, etc. but rather the internal parts. None of these are high-hour units.
Wondering if any of you Kohler experts have seen this or know the solution??
Thanks for your time.

?? on the model number. There are bulletins on the ECV governors. So what happens if you don't flick the arm? Totally different thing here. Honda GCV160 A stray few of them have an issue that you had to flick the governor arm to start.Honda changed the spring to something with less spring body but a slightly higher tension. Maybe it is simple as an updated spring. Wouldn't that be nice?
Mechanical Governor Modifi ed Adjustment Procedure (Surging)
There have been isolated reports of some newer ECH/ECV engines exhibiting a high-speed/noload surge.
This is most commonly reported of new unsold engines with minimal hours. The surge
typically ceases with PTO engagement (load). The surge may cease with several hours of
normal operation.
Remember, there are many possible causes of an engine surge. Specifi cally, run quality
faults that are not caused by governor components/adjustments.
The modifi ed governor adjustment illustrated below may resolve the surge. Testing suggests
this may resolve surging conditions on older engines as well.
Standard Governor Adjustment standard Governor Adjustment Modified Governor Adjustment ed Governor Adjustment
Standard Governor Adjustment
1. Loosen fastener.
2. Turn governor shaft counterclockwise to stop.
3. Secure fastener.
Modified Governor Adjustment
1. Loosen fastener.
2. Turn governor shaft counterclockwise to stop.
3. Slightly back off stop.
4. Secure fastener.
5. If surge persists, make incremental adjustments in the same manner.
6. If/When speed becomes uncontrollable, adjustment has been backed off too far.
7. If ineffective, return to standard governor adjustment.
8. Check speed setting and adjust as necessary

This isn't really a surge. Run fine except when the governor lever is "stuck". Pop it loose and they run fine.

Bles, The next time this happens don't be in a big rush to unstick it and carefully check the linkages as the see the source of the bind is and go from there. It as a simple it get in a bind.

This probably something we all need to know about or least it in the back of minds.

Not only that but also carefully consider whether it is the governor making things stick,or a binding throttle shaft or plate (I've had throttle shaft levers that wore a ridge and would hang up on the throttle stop screw, and one where throttle plate wore away enough into the carb bore that it would stick there until popped back loose)

Thanks. Seems to be internal. I haven't checked the other one, but it's doing the same thing. I'll have to get to it and remove linkage, etc. to confirm.

And please let us know what you finally find to be the root cause as we might start seeing the thing later this year.
