Does anyone today make a throttle damper that would keep a Honda GX200 or HF 212 engine running at a constant speed?
Decades ago I remember seeing such a device and as you increase the engine RPM this device would not allow the engine to surge faster keeping the butterfly valve at the setting you are using. I do not remember if it was a captured soft spring or was even a small pneumatic cylinder that did this but it was pretty neat and worked very well.
It was used in rough terrain to prevent the bouncing and shocks of a moving vehicle to cause the engine from increasing speed.
