how to modify your Honda EU2000 to run out of gas

Ethanol once again reared it's ugly head.

Despite being treated with Marine Stabil, my EU2000I would only run with the choke being partially on.

As usual, the carb tear down showed the mess this stuff leaves after it evaporates. All of my other small engines have a gas shutoff valve, which I use to run all the gas out of the carb and avoid this problem.

While I had my generator apart, I noticed the big On/Off switch has two functions. One turns off the gas, the other kills the spark. I disconnected the plug in the pic shown, which has a green and black wire on the right hand side. Now, I can turn the big switch off and only the gas gets turned off. The generator will run for about 3 minutes on what is left in the carb, and shut down.

Be sure not to have anything plugged into the generator when you shut it down this way.

To restart, just turn the big switch back on, give it full choke, and it will start on the first or second crank.

It's not that big of a deal to pull the carb on this generator, but even so, it takes about an hour. If you disconnect the kill switch, and run it out of gas after you are done, you won't have to worry about the carb getting gummed up.

I am sure this violates at least 87 federal laws and probably 580 state laws, so as always, proceed at your own risk. If you decide it's not for you, simply plug the connector back together and tear down the carb every time it sits up for 90 days.

So yer saying the switch/valve we see in the bottom right controls fuel and power all in one?


I've recently taken the cheap way out for the gennies as little as I use them, which is pretty much during a hurricane. I run them at least once a month to keep them up.
I have a Honda knockoff 13hp 75kw or 7500kw (somewhere in there whichever it is, I'm a plumber remember?) some of the parts even have the Honda logo on it, the biggest difference I've found is that the actual Honda holds almost 2qts of oil, mine holds 1.
Some of the parts, like the fuel shut off valve, look just like the parts on the cheap blue 900-1200 units you can get at Northern tool for $100. The fuel shut off is an actual physical valve, but it has never worked. On or off, it still runs..
Strange?
Nay!

Honda provides a fuel drain. It's on the bottom/front of the carb. Unfortunately, it's piped to the bottom of the base of the generator and that holds gas. They already recognized the problem, but their solution leaves a lot to be desired.

That little generator pretty much got me through Ike. With the 6 gallon extended run tank, it runs over night and to refill it, you don't need to shut down the generator. I really didn't want to modify this one any more than needed. A kill switch would be easy enough to rig up, but I went for the KISS theory here.

I sure wish someone would initiate a class action damage suit against the ethanol industry! Im not a real big fan of class action suits, but I would join up on one against ethanol. boat engine, lawn mower, weed-eaters, chainsaws, blowers, truck engines!

Ethanol just needs to go the hell away!

You are a life saver Mont! I just bought one of these generators and was about to install a fuel shutoff valve per other users on Youtube. This is so much simpler however. Wonder if I ever decide I want the option to be able to shut down for such as refuel, would I splice into which wire (green or black) to install a switch to allow shutting down as before using new switch and use the OEM switch to let it just run out the fuel? Otherwise, your wire disconnect works great and using it now on mine. Thanks for this even as an older post, it has proved invaluable to me.

Not sure about in H-town but the new Walmart Murphy stations in DFW area now have Ethonol free gas pumps. It's about a buck more but I use that in all my yard equipment, generators and boat.

Also be careful with the pumps that say 10% ethonol, my brother n law had a new boat and the motor burned up. They tested the fuel and it was 25% ethonol which voided the warranty, he's trying to settle with the station he always buys gas with in East TX.

They are remodeling a Murphy here in Katy and they have a sign up that says they will start carrying e-free gas.

I was always told it still leaves gas in the bowl and you have to drain the bowl. ???

Me too, I really only use my Hondas at the lease so at the end of the season i drain the gas, run it empty then run some of this into the system....this stuff and seafoam is the answer to a lot of ethanol problems. Never had any luck with stabil, I threw all of mine out

I agree and just happened across this post thanks to a Google search. Go figure! I can't believe how quiet this thing is either. Getting a second one to run parallel soon for my RV to run an AC also. My trailer has a residential fridge and mounting it to bumper to power fridge while driving.

I have a 1000 and a 2000. While I've never had issues with them, this seems like a great idea. I will have to look at them once I get home, and figure out where to mount a momentary switch so I can kill it either way. I'd love to be able to run the fuel out of the carb, but also just shut it down with a kill switch.

The 1000 I acquired overseas, guys traded it to me for some stuff and they couldn't get it working. Pulled the carb and it was NASTY. Fixed it up and made some orings/gaskets work from what I could find in our supply and it's been running great ever since. One day I will get an actual rebuild kit for that carb and replace the make shift seals, but for now she runs like a top.

Agree, eith a switch on the green or black should allow you to choose and plug the two wires back together if a switch was installed. Just not sure which wire needs the switch. Guessing the green, but would like to be sure before cutting into the wires.
