Advise on a Honda Generator that will not run


Pulled out the genny and she would not start. Cleaned the carb and she will start briefly but shutoff and she will only start with the choke on.

All suggestions are welcome and appreciated.

1. new fuel
2, cleaned card. jets, gaskets replaced.
3. removed the finger filter
4. new spark plug
5. changed the oil

a. air filter in or out same issue
b. fuel is flowing, just not sure how much should
c. ordered a new fuel pump.

Check the oil level, most have a low oil shut off.

Barring a vacuum leak (like a cracked plastic spacer between the carb and motor), it still sounds like a carb problem.
I had one do this and had to eventually replace the carb.
Problem fixed

At least there's hope

The low oil shutdown could be faulty also, un plug it and try to start it, only takes a minute to eliminate it as a potential problem...after checking the oil level of course...

is there a fuel filter? If so might be worth cleaning out or removing and seeing if that fixes your problem. I agree with Vandy, sounds like some sort of fuel delivery issue to me.

Below is the link for a great video on how to clean the carb of a Honda EU2000 generator, I would bet my last dollar if you follow the video and clean the jets out really well your generator will fire right up.

Good Luck!

Great info!

I oil try the low oil switch. I removed the finger fuel filter from underneath the tank.

Once in my many times of cleaning that darn carb, she turned over and started running rough. She would not run strong enough for the strator to produce power.

Here's a video of her running rough.

The oil sensor pretty much works or doesn't. I doubt that's your problem. Clean the carb again, especially the main nozzle and main jet. Also, if you can , take a dremel tool or pointy die grinder and carefully grind off the limiter tab on the idle mixture adjustment needle then remove it . Be careful to record its original setting by screwing it in till it bottoms and counting turns. Soak the carb for at least a few hours in a mixture of carb cleaner and if you can find it Mechanic in a Bottle. Blow all passages out with compressed air . I just went thru 2 eu2000's this way and it helped a lot.

Since it's partially running, searching for an electrical/electronic problem should be way down on the list of things to test. The sensor was an easy one, so no harm trying that. It's fuel delivery related.

I've had similar problems with a Yamaha genny. I just needed to be more thorough in the carb cleaning. It took two cleanings.

It's such a pain that I RELIGIOUSLY go through the process of making sure that I run the generator dry (I even add Stabil to the last tankful, in case anything remains in the carb system) before a long period where I dont plan on using it.

Probably your Honda sat for an extended period, the fuel evaporated, leaving that varnish-like residue. I've heard that today's fuels can start to break down in a month's time. Stabil helps a lot.

if it runs a bit w/choke,indicating an excessively lean mixture, my money is on a clogged jet. a tiny grain of sand will stop the show. also gum or other funk will yield similar results, as previously stated, fuel stabelizer,and frequent excercise,and super clean fuel, will go a long way to prevent issues like this. best of luck sorting it out

The key to me is that you say it runs with the choke on, that tells me it is not getting enough fuel, I agree with Kacyj, hook and pacificobob, take the carb back off, completely disassemble it and soak it in carb cleaner and then blow it out with compressed air. Also if it is going to sit for extended periods be sure to drain the fuel out of the carb using the drain screws provided. They're the ones with the small plastic tubes connected to them. Good luck with it.

I think that Hook nailed it with the fuel comment. I have had more problems with small engines in the past few years than I ever did in the past. My problem is compounded by the fact that all of my motors sit for months at a time.

Looks like I better do a better job of storing them. CA gas is the worst!

Put the carb in the ultrasonic cleaner. The ultrasonic gets in all the little nooks and crannies of the carb and cleans in places where the carb cleaner doesn't reach well.

A little sarcastic, there?

I got an ultrasonic cleaner about 10 years ago. My buddy who has a motorcycle shop got one shortly after I did because it did such a great job of cleaning carbs and other stuff. I'm guessing there are a few ultrasonic cleaners in Baja for the same reasons.

I'm guessing by your response that you don't have an ultrasonic cleaner.

If fuel is allowed to sit for a while, it tends to gum up the carb. An ultrasonic cleaner is likely to be helpful in cleaning the carb.

Here's one for pretty cheap, would probably work fine for a small carb.

The jets and passageways in these small engines are very tiny, the smallest bit of deposit or dirt will alter the fuel flow sufficiently to make them run bad or not at all. I agree that a good cleaning is needed, however an alternative is to replace the entire carb. They can be had new for $15 - 20 USD on line. Problem solved - until next time as Vandy mentioned.

Mexican carb rebuild. Rev up engine as high as it will go, stick thumb in carb., do that 4-5X. This works a surprising percentage of the time.
