I'm confused. How can an electrical switch cut off the fuel? Is there an existing solenoid valve in the fuel line? Thanks.
On edit: Is the OEM fuel pump electric?


The fuel pump is mechanical. Like many small engines, It has a line connected to the crank case that uses the vacuum/pressure impulses created from the piston running up and down to activate the fuel pump.

The round run / off dial selector when turned to the off position shuts off the fuel supply. It also kills the engine at that same time. That leaves the carb full of fuel. So by adding the remote kill switch for the engine, (which you don't use unless you need to stop the generator right now), it allows the engine to run out of fuel by itself instead of being shut off when the dial is turned to the off position. The Hutch Mountain add on only changes how the engine is shut off. By running out of fuel. Again the kill switch they include is not used unless you need an immediate engine off shut down for what ever reason. Honestly for twenty something bucks, it is a fantastic mod.
My eu2000i took about two minutes to run out. Sitting three days and demonstrating for a neighbor, it started in 4 pulls.

As for the hard to start problem the gent from NY mentioned. I would check the impulse rubber lines that make the fuel pump work and make sure they are intact, no leaks, cracks, poor connections ect. Then I would just for the heck of it remove and clean the carb with carb cleaner and compressed air. Not just a rinse, but take out the brass jet rod. Really clean it out. I suspect it is a fuel delivery problem and not a run ability issue that a carb would cause. Cleaning the carb will only help things.
You could remove the fuel line to the carb, hose barb it to a little bit longer hose that goes into a cup. And pull the cord to see if you are getting fuel when trying to start it. It should pulse fuel into the cup. You might have a weak or bad fuel pump. It starts easy after running because there is fuel in the carb bowel already. It sounds like a fuel delivery problem.
You are to far away to stop by and help. [emoticon]

My EU2000i always starts with 1 or 2 pulls if it's been run in the last few days. But if it sits for a month or longer, it's a good 20-30 pulls to get it started. But after all those pulls and finally starting, if I shut it off, it restarts in 1 or 2 pulls.

Anybody else have this problem and been able to fix it?

Been like that on every Honda 2000 I've ever used. IMO, save the 20-30 pulls. You know it's not going to start right away. It takes less than a minute to remove the side cover and airbox cover to use some starter fluid/carb cleaner/wd40/brake cleaner/gasoline to get it to fire on the first pull.

I noticed that on small engines, when you have empty carburetor bowl, it takes about a minute for gas to fill it up.
Since I always run my Honda 3000 dry before storage, I always give it couple of minutes to soak, before I pull the cord.
Actually I do the same on my 1922 Ford T.
My 3000 is about 17 years old and only couple years ago I put new carburetor since rebuild kits are not available.
It still starts on 1st pull most of the time. Still have the battery that come with it in dry stage, with acid in the bottle. Never felt the need for electric starter.

…. And for those that need more than a Honda 2200 but don’t want to lift a heavier load don’t forget: … get 2 Honda 2200 = plenty of watts & easier to lift…….And not made in Communist China….

How? The device is described as a switch. To cut off fuel, one needs a valve. Is it both?

The round run/off dial when turned to off, shuts off the fuel supply and shorts out the spark plug lead. So adding the remote kill switch allows it to run out of fuel. You don't even need to use the switch. Just let it run out of fuel. Approx 2-3 minutes.


On a side note.
I am reading some posts from many years ago that state that there is some fuel left in the carb bowl after running the gen to stall.
I may have a look on mine.

Always remove the side panel and drain the carburetor via the drain screw, to eliminate any gasoline in the carburetor bowl.

Draining carburetor is overkill. Nothing wrong with it, but extra work.
I have several machines with Honda engines, like pressure washer, concrete saw and grinder. Some of them 20 yo and running carburetor dry always work for me.
Never used gas stabilizer, but if gas gets older than 2 years, than I suck it out and dispose.

Actually pretty easy to drain. Flat blade screwdriver...turn it, watch gas drain 30 seconds, close it.

Back years ago I installed a piece of 1/4" tubing from the intake assembly into one of the intake tubes, drilled a hole in the bottom of the 2000 next to the bowl drain tube....
After my 2000 has sat for a while and won't start after a couple of pulls I just squirt starter fluid up that external tube and the 2000 starts after the 1-2nd pull..

I did this to a couple of buds 2000's too... A life saver.
