I have a Honda eu3000is generator that didn’t run, well Barkley ran on full choke. I unplugged all the wires to the inverter and started the generator and it fired right up. When plugged the inverter back I while it was running it shut down again. Does this mean the invertor is bad? Or could it be the stator?

I would suspect that the inverter is fine and would look towards carburetion. The inverter, in addition to supplying the correct voltage and current, monitors the current being drawn by your connected load. It controls that stepper motor on the top of the carburetor and increases the throttle to increase the engine power to support the load. (Mechanical power in = electrical power out.)
Start the generator and then add a small load to the outlet, 100 watt light bulb or something. I use a space heater that I can turn on just the fan. See if it still stays running. Then increase the load (with my heater I go from fan only to the first level heat 1000w) and watch the top of the carburetor to see if the inverter increases the throttle to compensate for the increased load. By the sounds of what you are describing, it will go to full throttle and the engine will die because of a restriction on the available fuel. If that is the case, take the carb off and clean it. Or if you are not the carburetor rebuilding type, buy a new one.. they are only about $80. Not a bad fix for a $2000 generator :)

SOURCE: honda em2500 starts, runs 1 minute, quits and will not restart

If the oil level is low it will do this, but I also know this to happen when the oil is very cold (thick) an won't fow back own o the crankcase where the oil sensor is. The slow return results in a low oil level. My solution is to start it, when it dies wait a couple of minutes and retry... after a few starts, the oil will warm up, thus flowing back down faster and it then will run. Another option is to use a thinner oil ie;5-30w.

SOURCE: Coleman 6250 generator runs rough

Fresh fuel? Does carburetor have adjustable jets? Turn the high speed jet (at bottom of float bowl) about 1/4 to1/2 CCW (looking at bottom of bowl). If no improvement, carburetor should be torn apart and cleaned. This also applies if there are no adjustable jets. Is there a fuel filter anywhere?

SOURCE: troy bilt 5550 generator no start please help

fuel, fire, mechanical. Miss one and she won;t run. Are you sure the gas was good? Not some old can laying around that may have turned or become water contaminated? If it was fresh gas, then take off the air cleaner and spray a little wd-40, or ether, or brake cleaner whatever is flammable into the carb throat. Just a 1 second shot is all it should need. Try and start with that. If it starts and then dies quickly, still a fuel problem. maybe a gasket is damaged, or the jet is clogged. When you said you checked for fire, you acutally took the plug out and had it grounded while spinning the motor and saw spark? If you saw a hot spark then you have eliminated fire. Mechanical not likely if it was running well a short time before. If a valve was damaged, it would still run but not too well. My gut feeling is it is related to fuel.

Testimonial: "thanks for the great help i did try fresh fuel and drained the carb bowl but still same prob its a head scratcher i really thank you for your input."

Honda em 5000s runs but no power. took off alternator cover, AVR looks fine, can not find bushing?

Could be a bad breaker, A blown fuse on the generator (would be wired into the wiring of the alternator and taped up), bad connection on generator wiring or faulty generator wire. You may or may not need to replace the generator assembly.

I just cleaned the carb and now it starts and runs fine, but starts burning oil after a couple of minutes. Did I get it wrong on assembly?

There is a series of spacers and gaskets that go on in a specific order. I can't remember offhand. If you get them on wrong it can mess up the alignment of the choke control which causes it to bind up and not move freely. That can make the engine run rich and smoke which makes it look like it is burning oil.
Check online for an exploded view of the gaskets and spacers along with the bracket for the choke control. Make sure they are aligned properly.

Why does it start with the key when cold put not when its hot put i can pull start it with one pull?

You may have a cylinder head gasket problem either that or if this is a two stroke engine crank case pressure is critical, once hot there may be a pressure leak not enough to stop it from running once started but enough to stop you starting when warm, alternately a fuel evaporation problem not getting to pot before evaporating due to heat or blocked fuel jet when warm, if this unit has a choke is it disengaging a warm choked engine rarely starts and floods out smell of petrol will be high.
check that plug is not breaking down under pressure try another one check plug gap when warm it varies. hope this helps

Honda eu3000is does not operate without choke

It sounds like your fuel mixture is too lean, closing choke is richening the mixture, by closing off air

Honda eu3000is generator surges

Inverter Generator Benefits
  • The EU3000 series generators are inverter generators. The generator features an alternator, which produced high-voltage, multi-phase AC power. This power is converted to DC power and then converted back to AC. This process is controlled by a microprocessor and is necessary to provide stable, consistent power capable of running equipment sensitive to power surges. This type of generator provides higher fuel efficiency and lower operational noise ratings in a lighter model than home and work generators produced by Honda.

EU3000i Handi Specifications
  • The Honda EU3000i Handi is a 3,000-watt inverter generator that features wheels, folding handle and a recessed convenience light. The engine is a Honda GX160, which features a 163-cc displacement. The AC output is 120 volts, with an average rating of 2,600 watts and a maximum production of 3,000 watts. There are three receptacles to include a 20A, 125-volt duplex and a 30A, 125-volt locking plug. The DC output is 12 volts and 100 watts. The EU3000i can hold 1.56 gallons of unleaded fuel, which will provide consumers with 3.6 hours of run time at 25 percent load for 7.7 hours.

Wont run off 1/2 choke

I had a problem with a honda generator that would only run on full choke. I removed the carburetor and cleaned the main jet with a wire and carb spray. Problem solved. Fuel stabilizer should be used with todays gas mixtures that have ethanol in them. Hope this helps.
