Shouldn't be happening, possible causes :
1. Leaving choke on for too long and flooding the engine while attempting to start.
2. Carburetor flooding due to stuck needle valve or dirt in the carby fuel bowl.
3. Drain screw on the bottom of the Fuel Bowl not tightened.
4. Fuel bowl seal faulty.

The floater in the carburetor is not working properly. Take it apart and remove the rust out of the pan - see if it still can work for you. Leaving gas in the generator, even for less than 6 months can stop the carburetor from doing its job. The pin (Rubber end) and the seat need to be cleaned and also the balance pin. Use a good spray and blow all the channels open. Put together and let it run. Thank me later.

Yes all parts are available including the outer case, but the s/h one needs to be cheap as the cases are expensive...

No, but you can add an aftermarket one, simple to install.

Hi, I am not sure, sounds like you have the USA plug which is a 2 pin. As I am in Australia we have a different type of plug ( 3 pin flat).
I would recommend contacting a local Honda Generator Dealer.
Cheers.

this size genset wont run a pressure washer think 5 to 6 kva my gentrax 3.5 won't even turn over a mid size girni I think it is 1700 watts so multiply that by at least 5 to allow for start up current draw, and you get 8500 watts so you you need at least a 6 kva and still it mite damage that size genset trying to start it. air compressors and pressure washers are almost imposable to use without the very largest genet's, like 8 kva for safety and not to damage your genset.

check reset button on front of genset push to reset

Sorry David..
This is out of my league....

Hi David, I don't believe so, usually like for like 2Kva + 2Kva. Suggest you contact Honda MPE to double check.
Cheers, Greg

no you can not

Sorry, to difficult to guess, hard to know if its electrical or a carby problem, did you try a new spark plug? or check to see if the air filter is blocked? I think it needs an experienced eye to look at the problem.

fuel cap vent is closed

Hi, you have 2 options, one is to keep a manual log and the other is to purchase an electronic tacho/hour meter which is a small device that you attach to your generator with a 'probe' wire that wraps around the spark plug lead and by measuring the spark impulse it gives engine revs and importantly the engine running hours, it also comes with its own internal long life battery so it is very easy to install and set up.
I have been a long time retired now, but the ones we used to sell were called Tiny Tach, ask at your local Outdoor Power equipment shop, they should be able to assist.

Just checked the manual. It appears that on start up the red light will blink for each 50 hr block of operation.

Sorry I can't assist you, please take the Generator to a Honda MPE Dealer, it will require someone to inspect it and define the fault.

check fuel cap vent

Sorry, but a difficult one to answer. Did you try running the Generator unplugged and without load? also then try using it to run a small appliance or electric drill. A process of elimination of the problem is required. Suggest then if the problem persists you will need to take it to a Honda Dealer for further testing.
Good luck...

was the instillation done by a licensed electrician in Australia it is against the law other wise as you can kill people in houses father up the grid. when genset is started to power your house.

Hi Dave, I avoid e10 and only use standard unleaded.
I'm no expert but have been told don't bother with it.
cheers
Mark

Hi Dave,
Best to avoid E10 fuel, the ethanol in the fuel is hydroscopic and will absorb moisture which may condense out into water in the fuel tank

also the etholal separate's out of the fuel over time and will case engine damage on next start-up. it will also eat your fuel lines in your fuel system
sorry for poor spelling I am a mechanic not a accountant.
any way the Honda is not designed for e 10 don't use it. it is not to be used in outboards for the same reason long time frame betten uses of engine and the fuel line issue. and engine trying to run on pure ethnol after it has separated out of the host petrol causes massive engine damage.

I Have always used 95 ULP never a problem, don't use E10.

Hi Rob, 240v 50 Hz is correct, not sure where you would see 60 Hz advertised, probably a mistake, but to be sure give Honda MPE Melbourne a call to check.
Cheers.

Hi Greg, I think you have misunderstood my question. When I first bought my EU20i I used a power meter to check the load I had plugged in, this meter provides a display of volts, amps, watts and frequency (Hz). The meter showed the output of the generator was 240 volts, 60 Hz. When I contacted the supplier they said I was getting good value for my money as it was outputting a higher frequency than the advertised 50 Hz. I will take it back under warranty (3 years I believe), I didn’t want to do it over summer as I bought the unit in case of blackouts, it has been one of those things that I need to get around to doing ASAP. Rob.

Hi Rob,
Did you ever resolve this issue.
I have a similar problem with an EU20i.
The label on the generator indicates the output is 240V 50Hz, but when I check, the output it is actually 240V, 60Hz.
I have an idea about how to solve the problem but don't know if I am right and haven't tried it yet.
regards,
Ken
