Generator starts and runs in choke position only. shuts down in run position.

Here are some common troubleshooting steps to help you identify and potentially resolve the problem:

1. Fuel Supply:
   • Check the LP (propane) fuel supply. Ensure that there is enough propane in the tank.
   • Check for any obstructions or kinks in the fuel line.
2. Air Intake and Exhaust:
   • Make sure the air intake and exhaust are not blocked. Lack of proper ventilation can cause the generator to shut down.
3. Choke Position:
   • Check the position of the choke. If it's set to "Choke" for starting, make sure to gradually move it to the "Run" position once the generator has started.
4. Fault Codes or Indicator Lights:
   • Look for any fault codes or indicator lights on the generator control panel. These can provide clues about specific issues.
5. Oil Level:
   • Check the oil level in the generator. Some generators have a safety feature that shuts them down if the oil level is too low.
6. Spark Plug:
   • Inspect the spark plug for fouling or damage. If needed, clean or replace the spark plug.
7. Fuel System Issues:
   • Inspect the fuel system for any leaks or issues. LP generators may have a fuel filter that needs to be checked and, if necessary, replaced.
8. Carburetor:
   • The carburetor may need cleaning or adjustment. If it's clogged, it can lead to stalling issues.
9. Battery Voltage:
   • Ensure that the generator's battery has sufficient voltage. A weak or dead battery can affect the starting process.
10. Generator Load:
    • If the generator is under a heavy load, it may shut down. Try starting it without any load and then gradually add loads.

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 not in use leaving a film behind. This residue will plug and interfere with the fuel passages and metering orifices of the carburetor. 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.

Give it a shot of starting fluid. If it runs initially, then most likely the jets on the carbureator are clogged. You should remove the carb and clean/rebuild it.

This generator is equipped with an auto choke. What is likely occurring is as the engine warms up the choke is returning to the normal choke off run position leaning the mixture two lean to maintain operation of the motor.

This is occurring because the residual fuel that was left in the carburetor has evaporated and the gum residue is reducing the fuel flow through the carburetor. When the choke is applied the mixture is rich enough to support running and as the choke returns on its own to the run position the mixture leans out and the generator stalls..

Override the choke when the engine is starting to falter to confirm the problem. Continuing to attempt to run the engine possibly adding a carburetor cleaner additive to the gas will likely return the unit to normal operation.

If attempting to enrich the mixture by applying choke when the engine begins to falter does not work then a fuel flow problem to the carburetor may be the root cause. I would look for a plugged fuel filter or restricted fuel flow from the tank to the carburetor. What is happening is when the unit is at rest the carburetor is filling with gas and as it is running because of a restricted fuel flow the level lowers in the carburetor bowl resulting in a mixture to lean to run.

The running on choke is caused by a fuel restriction. Check the fuel flow from the tank to the carburetor.Change the fuel filter if it has one. If its good, then the restriction is in the carburetor. The generator is shutting down due to the low rpm coming from the engine. A carburetor rebuild may need to be done.

Sounds like the choke is not closing. Perhaps it has become detached from the manual throttle.
A simple test you can perform is to let it cool for an hour or more, remove the air filter and cover the air intake with your hand (making your hand a manual choke). If it starts right up, then the real choke is the problem.
There are two valves that you can see from the top of the carb. The one closest to the air cleaner is the choke. The other one is the throttle. Both valves operate through 90 degrees of rotation. The choke should close all of the way with the lever in the start position and be open all of the way with the lever in any other position.

Need more info,

Does it turn over??

Does it have spark??

Does it have fresh petrol??

What brand of engine & horsepower is it?Also about how long was it stored or last time it was run? The reason I ask is if it was stored with gas in it & a fuel stabilizer wasn't added to it,your primary jet is plugged in the carburetor(reason it will only run while choked).

leak at carburator gasket

Where can i obtain a manual for the 5500 gas generator
