3.26 ELECTRIC GOVERNOR INSTALLATION
AND ADJUSTMENTS - FORD LRG425
ENGINE (PRIOR TO S/N 0300065534)
General
These instructions presume no electrical test equipment
other than a multimeter for making the electrical measure-
ments called for on the following pages. If no suitable
meter is available, an inexpensive but adequate meter,
part number 22-188 is available from any local Radio
Shack store.
Many “governor problems” turn out to be installation
problems, particularly in first-time applications. Careful
attention to the directions provided will go far toward a
successful installation made in the least amount of time.
Quick-start Installations
If you are experienced in installing and adjusting Electric
Governor, follow these steps. Otherwise, refer to the more
detailed instructions starting with “MOUNTING-ACTUA-
TOR”.
1. Mount Actuator rigidly to engine location which will
permit a short, straight linkage to the carburetor or
fuel valve. Avoid very hot areas.
2. Mount controller in a dry, fairly cool location. Acces-
sibility for adjusting is required.
3. Wire per appropriate included schematic, using #16
wire.
4. Set up fuel linkage. This is critical, so review the sec-
tion titled “LINKAGE”.
5. Hold linkage for safety, and start engine.
6. Adjust engine speed to desired valve using High
Engine pot. Turn CW to increase, CCW to decrease
speed.
