Carburetor Assembly
Varnish buildup from ethanol-blended fuel restricts the microscopic orifices in the main and pilot jets. While the engine may start using the enriched fuel from the choke or primer, it immediately starves for fuel once it attempts to transition to the run circuit, causing a lean-out stall within seconds.

Low Oil Level Sensor
This float-style sensor is designed to ground the ignition coil to prevent catastrophic engine failure. If the sensor is stuck or the oil level is at the critical threshold, the initial engine vibration and rotation during startup trigger the switch, immediately terminating the ignition spark to protect the internal reciprocating components.

COsense® Carbon Monoxide Module
Modern Generac inverter units feature an integrated CO sensor that monitors ambient air quality. A malfunction in this solid-state module or the detection of exhaust gas recirculation near the intake will send a digital kill command to the control board, shutting down the engine roughly 5-10 seconds after a successful start.
