clean out the carb

If you have a Yanmar engine...There is a hose that is connected to the oil pan in place of the drain plug directly under the oil filter that will have an end cap. This hose is used to drain the oil into a waste container. Download the service manual located at the address below and follow the instructions in the manual. http://www.martindiesel.com/Documents/New%20TNV%20DIRECT%20Service.pdfHope this helps.

FIRST THINGS FIRST. VENTILATED AREA,FRESH GAS, OIL LEVEL. IF ITS BEEN SITTING FOR MORE THAN 2-3 MONTHS THE CARBURETOR IS SUSPECT TO HAVE VARNISH PLUGGING JETS. START THERE. DARIN

Hi,
If a generator sits unused for a long enough time the generator magnets will loose their power and need to be "flashed" or recharged so that the generator will start to work again...

Here is an interesting discussion about that...

Here is another way to do it..

there is a screen in the tank at the shutoff valve best bet it to remove it and tear it out and use a in line filter where it is easier to replace

This likely has a diode module which rectifies a low voltage AC winding to do the charging.

Things to check: There USUALLY is a fuse on the low voltage winding. It SOMETIMES is within the generator covering.

Check for loose connections or broken wires.

The diode module is usually a 25 amp block about 1.25 inches square with 4 faston terminal connections.

Use a meter set to AC to check voltage on the AC terminals... might be around 18 volts or so.

Then on the DC terminals labeled + and - with meter set to DC.

To charge a 12 volt battery there needs to be about 13.75 volts or so.

there are just a few thing's that cause this, one is the voltage regulator is failing and the other is one phase of the three phase Alternator is open, u will need to have the alternator windings tested for continuity and shorts to ground, also a unregualted voltage test to determione if the voltage regulator is the problem.
