Overview

The Generac 0F92550SRV is a genuine Generac natural gas / LP (propane) mixer assembly with the electronic governor stepper motor, built for generators powered by Generac's GT-990 engine. The mixer meters air and gaseous fuel into the engine, and the stepper motor moves the throttle to hold engine speed as the electrical load changes. A worn mixer or a failed stepper can cause surging, rough running, hunting or unstable output.
