    Also, petrol and diesel degrades over time. Diesel & petrol last for 6 to 12 months in a tank. so if you haven't used your generator for over a year, replace all fuel.

    I've bought a lot of stuff from Omega and they service also although they are always backed up on service work. Oil pressure switches can get gummed up by dirty sludgy oil so keep clean oil in the engine. After oil change remove the oil pressure switch and flush it with diesel. While it is out crank the generator over until clean oil spurts out. Then reinstall the switch.

    The hard starting is generally caused by not following shutdown procedures of turning off the fuel and letting the engine die from lack of fuel. If you just turn the key OFF fuel left in the carburetor will gum up the jets and float in between uses.

    I'm not mechanic, but it could be a choke not working properly if it runs fine when warm.

    "A choke on a lawnmower engine, or any engine with a carburetor, is a device that reduces the airflow through the carburetor. It causes the fuel-air ratio to be richer, that is, more fuel and less air. This helps most carbureted engines to start while cold and before steady fuel flow is established, but the rich mixture reduces the power and efficiency of the engine tremendously. Leaving the choke on will produce hydrocarbon and carbon monoxide emissions and may cause the engine to stall as soon as any load is placed upon it. That is why engines require either manual release of the choke or have an automated device to back it off. Excessive use of the choke will generally result in fouled spark plugs."

    Gasoline deterioration can sometimes be an issue that diesel engines do not have. Gas that is part ethanol is especially bad and has a short shelf life of about 3 months. After that it can turn into varnish. As one poster stated, carbeurator cleaner might help.
