This generator has maybe 100 hours on it and I use it maybe 15-20 hours a year and run it for 30 minutes a month when it is not being used. I tried to start it for a 30 minute run and it started and ran for 20-30 seconds and stopped. While it ran, there was black smoke coming out the exhaust like it was being choked and it died like it was being flooded. I took the spark plugs out and they were wet. I ran the starter with the spark plugs out and droplets of gas
came out the spark plug holes. It obviously is way too rich, right? So, what could be the problem? Choke sticking closed? Some sort of carburator adjustment? I recently tuned it up and it has a brand new air filter. I tried it with the air filter off and it did the same thing.

I would appreciate any help/ideas.

Thanks,

Don

is there any dirt in the bottom of carb bowl when u take it off? if yes clean it and re install the bowl and run engine if possible, then take the carb bowl off again and check for dirt, if dirt is present replace the fuel line going from the tank to the carb, if possible install a universal fuel filter u can get really small ones to fit in tight spaces. the smallest piece of dirt can cause the needle to stay open enough to flood the engine. double check and make sure the choke is opening correctly.

I have an EV 6010.  It has over 5000 hours on it and it generally runs very well.  I've ben told I should get up to 10,000 hours out of it.  It requires maintenance like anything else.  The best guys in the country (USA) are the guys at Hicklin Power in Iowa.  They are friendly and know this generator like no one else.  In my experience, I've found that the automatic choke, despite it looking normal, needs lubrication on occasion.  I simply spray a silicone or other product (WD 40, etc) on the linkage which does the trick.  Since I put a lot of hours on this machine, I use the maintenance kit every 250 hours (which doesn't apply to you).  It's important to have the precise Honda spark plugs in the machine (NGK).  I tried a different plug and wound up with nothing but trouble.  Make sure the proper (original) plugs are in the machine and try simply lubricating the choke linkage and see what happens.  You may be pleasantly surprised.

Knowing that it has an automatic choke will help to diagnose his problem.   You've probably pointed the user in the right direction.   Auto chokes (enricheners) are convenient but are also more complicated and do need attention.   That would be one of my first places to look. 

If you remedied your problem with the gas flooding your engine please let me know what you did because i am having the same problem.I changed the float valve,changed the plug caps all to no avail.reely need help

I have the same problem with my EV 6010 . I think the fuel pump is to powerfull for the float to shut off. did you ever fix your problem?

Your generator has a fuel pump?  Where's the fuel tank located?

IF IT STILL SHUT DOWN TRY THIS. THERE IS A WIRE COMING OFF THE TOP OF IT IF YOU REMOVE IT  START THE GENERATOR IF OK ..REPLACE SENSOR...I WORK ON THESES UNITS HERE IN CONNECTICUT ALL DAY..I HAVE ALL THE PARTS YOU NEED FOR A CHEAP PRICE.
