  If your Generac Power Systems Portable Generator engine “hunts” or falters, it could be because the choke is opened too soon. Move the choke to the halfway position until the engine runs smoothly. If the issue persists, the carburetor may be running too rich or too lean, and you should contact an Authorized Service Facility.

Why won't my Generac Power Systems Portable Generator start or runs rough?

  If your Generac Power Systems Portable Generator engine will not start, or starts and runs rough, several issues could be the cause. First, ensure the fuel shut-off is turned on. Check if the air filter is dirty and clean or replace it. Make sure you have gasoline in the tank, and if the gasoline is stale, drain the tank and fill it with fresh fuel. Ensure the spark plug wire is connected to the spark plug, and replace the spark plug if it's bad. Drain the fuel tank and fill it with fresh fuel if there is water in the gasoline. Put the choke knob to the No Choke position if you are overchoking. Finally, ensure that the oil level is not low and fill the crankcase to the proper level.
