Is the governor spring directly connected to the throttle plate?

The governor spring is typically not connected directly to the throttle plate; instead, it utilizes a linkage mechanism that connects the governor to the throttle system. This linkage allows for the governor to control the position of the throttle plate indirectly by responding to changes in engine speed. The primary function of the governor is to maintain the engine speed within a desired range, adjusting the throttle position as needed to increase or decrease power output based on load demands.

In many engine configurations, especially in mechanical governing systems, a physical linkage (which may involve rods or levers) transmits the governor's output to the throttle plate. This design allows the governor to function effectively without a direct connection, contributing to smooth engine operation and response to varying loads.
