I am having trouble starting after it set for 6 months. I drained the gasoline and put new gas in. It cranks with starting fluid but will not keep running

Remove the float bowl and clean out the debris where the bowl nut screw into the carb. Also make sure the bowl nut itself is clean. The fuel jet is directly above the bowl nut. When they sit for any length of time water from condensation causes corrosion that falls to the lowest part of the carb and clogs the jet. Check fuel flow by turning on the fuel while the bowl is removed. It should fill a spray paint can lid in 8 - 10 seconds or less. Make sure to spray carb cleaner into the bowl nut threaded area to clean the tiny jet orifice hole. You may have to use a toothpick to remove debris in this area. Do not force the toothpick into any holes. Use it like a scraper. Let me know if this does ot get you going. There is more that can be done.

Hi again. I have to find you an on line source for a manual so you will know what to look for. Be patient we will solve this mystery. Expect a good solution within 10 hours. Kelly
The more I researh the more I find out there are actually 2ngines that came on this generator. One being a Honda GX270 / GCAB- and the other being a Subaru 9 HP OHV engine. Both carbs are similar.
The very first thing you do is take a picture of the linkages for your governor and carb. Not doing this can result in not connecting the linkages correctly after removing the carb.
Before carb removal:
1. Turn off the main fuel line to the engine.
2. Remove the main fuel hose
3. Use a catch basin and check incoming fuel flow. It should be a rapid gravity flow of fuel.
If you still do not have good fuel flow from the main fuel line:
1. Remove the fuel tank cap and see if fuel flow increases. (Vapor lock check)
2. Remove the inline fuel filter if installed and check fuel flow
3. Worst case... there is something blocking the fuel tank outlet port.
Known good fuel flow to carb:
1. Remove the carb. (AFTER YOU TAKE PICTURES!!!!!!)
2. Remove the float bowl (Again)
3. Using a thin bladed screwdriver... remove the BRASS throat jet located inside the barrel of the float bowl nut threaded area. (CCW to remove) This will be about 5/16" inch thick once removed.
4. Set the jet aside and remove the BRASS fuel tube (CCW to remove) This will be about 2 inches long.
5. Clean the Jet and the fuel tube with carb cleaner. The jet will only have a pin hole.. the fuel tube should have at least one hole in the side of it that must be clean along with the full length of the fuel tube.
6. Shoot carb cleaner into the hole where the fuel tube and jet were installed.
7. Lift the float while carb is inverted and spray carb cleaner in the needle and seat area until you note carb cleaner exiting the main fuel connection.
8 in the throat of the carb as you would look at it from the air cleaner side there should be one possibly 2 BRASS tubes facing you or at least visible. Spray carb cleaner into BOTH holes.
8. Re-install the fuel tube in the base of the carb.
9. Reinstall the jet
10. Install float bowl
11. Install carb and connect linkages AND springs in the ORIGINAL positions
12. Start engine normally
This should get you going... if not... then the carb is going to have to be soaked in some B-12 Chemtool for about 6 hours and then blown dry with air pressure.
There should be fuel flow with float bowl removed... anytime the float is below horizontal. If this is not happening... the engine will never run normally.
One more oh by the way.... make sure the engine is full of OIL. There is a chance the Low oil level sensor is shutting off spark. Starting fluid can make an engine diesel even if there is no spark. Just for grins check the spark..... after your make sure the engine is full of oil.
Please update me on progress.
