- A servo is a control arm both directions electrical controlled by speed regulator box
- The regulator senses 60 Hz to tell it what to do
- 12 volts for servo control. Need to match servo throw length to carburetor throttle arm. Longer arm is better to use all of servo throw length. This means faster + most precise speed control
- Reaction time to load change is instantaneous but engine response lag time from instant "no load to full load" cannot be improved that is an engine issue not a governor issue
- The servo must have an excellently anchored to engine mounting bracket
- No mechanical even a hydraulic powered governor is as precise as a good electronic governor. Today, tomorrow, next year frequency will remain 60 Hz.
Again, this is not plug n play mounting wise. I recommend 1/8" steel for the servo mounting bracket with three to the engine bolts attachment.
IMHO it is worth the bother. I will research online for general instrutions.
