How to fix generator need full choke to run
If you have not properly shut down the unit after use you will have likely had fuel remaining in the carburetor. The fuel will have evaporated while the unit was stored leaving residue behind. This residue will plug and interfere with the fuel passages and metering orifices of the carburetor. The residue reduces the fuel flow through the carburetor. Applying the choke compensates for the reduced fuel flow returning the fuel air mixture to a burnable ratio. If the unit runs with the choke on it is likely the carburetor is dirty. Be running the engine the carburetor will possibly clean itself. Make sure you remove any old fuel from the machine and replace with fresh. Allow the unit to run for an extended length of time attempting to return the choke to the run position. If you are able to return the choke to the run position you are on the way of solving this problem. You may need to run it additional time to completely purge the residue.
Additives are available to clean the carburetor and as a last resort if running with fresh fuel doesn't' return the motor to normal you may try it. For best results after mixing and running with the additives leave the unit overnight which may help to remove the remaining residue.
The shelf life of gas containing ethanol is about 30 days. In the future it is best to run the unit dry leaving ot fuel in the carburetor.
All else fails you will need to have the unit serviced by a small engine service center.
