Fuel left in gas tank for a long period of time caused gumming up of
carburator and possibly gas line. Generator will start, but runs very rough and will only stay running on half choke. Any possible fixes to remedy this problem?

Re: Stale Fuel in gas tank
Go to any auto parts store and get one of the products they have to remove the gum in the carburator and line. Some of the products are simply poured into the gas tank along with some fresh gas. good luck.

If you filled the fuel tank with gasoline enhanced with ethanol the fuel may be bad and caused the carburetor to gum up. Also Honda engines have a low oil sensor and from your description of the oil, can cause problems with the sensor and the engine won't start. Try changing the oil first and then adding a small engine gasoline additive that helps with stale gasoline starting problems.
Any time a weed wacker, chain saw, snowblower, leaf blower, or any 2 cycle machine must be stored for a period of time exceeding 6 months the gasoline must be removed completely from the gas tank and carburator. To do this simply run the engine until it runs out of gas then proceed to choke the carburetor and restart until no start up ocurrs this removes all fuel preventing the carburator from gumming up. This will allow you to store the unit for long periods of time without the worry of having to disassemble the carb. and clean next time it must be used.
If its stale possibly. If its carbureted and the stale gas has sat all winter with no stablilizer- quite likely the carb passages maybe gummed up and blocked- seen this myself..Drain old gas and refill. if fuel injected there may be another issue it should at least fire if the fuel is getting to cylinders and theres a spark.. if a Carb.. the same.. so if carb and no fir or no smell of fuel from exhaust- carb passages clogged or petcock..
These are all symptoms of a lean condition. Most likely cause is dirty carburator passages and jets. This could be from sitting up for a long period of time causing a build up of gum and varnish or it could be a gradual thing if unit sits for shorter periods between uses(4-6 weeks). The ethenol content in todays gasoline is such that each time the carb dries out in those short periods of inactivity it leaves a corrosive buildup in the carb. Over time this can cause clogging to the extent of a running problem such as you have. Im afraid a thorough fuel system(tank to carb) flushing-cleaning- adjusting is in order.
The float in the carburator is not working the needle & seat. Probably stuck from gumming & trash..Try tapping on the carb with a small object ...If this works put some carb cleaner in the fuel & run it for a while... This problem is caused by letting old gas stay in the tank & carb. If that doesn't work take the carb apart & clean the needel & seat area.. Good luck
Fuel will go stale if left for a long time. Drain and clean fuel tank and also drop float bowl on carburettor to remove any old fuel. If there is any sediment in the float bowl a carby clean could also be necessary.
Usually, the fuel filter gets gummed-up from leaving it in any kind of fuel for long periods of time. Fish it out of the tank and either clean it in spray-carburetor-cleaner or replace it. Check the condition of the fuel lines while you are at it. Proper storage is to drain the tank and run the engine until it stops. If still won't run, the carburetor internals may need cleaning and re-kitting. Make sure the spark plug is firing correctly. Hope this helps!
Gasoline goes stale after sitting a while and makes starting hard. Three years worth, it's more like jelly! You need to clean the tank, lines, filter, and carburetor. Run it for a while on a little fresh fuel after cleaning, then let it run out of fuel. That will remove most of the fuel from the carburetor. When you want to run it again, add whatever fuel you need, but allow it to run dry again. That's not prefect, but workable.
I had the exact same problem. There a few things you need to do first. 1) Make sure the fuel line knob is turned to the Open position; this knob is located under the gas tank. 2) Turn the power switch to on : it is a little red switch located near the pull-handle on the front of the generator. It needs to be on 'I' not on 'O' 3) Turn the choke lever on: it is a little steel lever with an arrow at the tip. Move the lever in the direction the arrow is pointing. 4) Make sure you have gas left in the tank: it may have evaporated or gummed up if you did mix in a fuel stabilizer before putting it away for storage.
If none of these things work , then you carburator may be full of water and gas lines gummed up. These Gens need to be started up at least once a month to make sure they keep working properly.
