Honda Generator

Hello,

I have a Honda EMS 4000, Generator, GE400-1003775.

Two problems.

First problem; when the generator is running and I switch on the Auto Throttle, it dies.

Second problem; it will start every time using the elec. start, but I have only been able to start it with the pull rope once.

Any help would be appreciated.

Thanks,

Jimmy

I think both are probably related to the idle jet being plugged. I haven't looked at your model but on most hondas, it is under the idle speed set screw.

Thanks Cheese,

While I am mechanical inclined, I normally don't have good luck with carburetor's.

Is there a link showing what and how I need to clean it?

Thanks

I usually remove the carburetor and disassemble it. Then I soak it for at least a couple hours in parts cleaner. Then with a can of aerosol carburetor cleaner I blow out all the passages and orifices paying attention and looking down the throat of the carb to make sure that I can see the cleaner spraying out of the jets into the throat.

It also never hurts to take pictures of the carburetor and all it's linkages before you start to remove it. It can be a big help when you reinstall the carb and need to get the linkages hooked up properly.

Go to U-Tube and enter "clean Honda carb" and several videos will show up, below is a link to one of them. Have a good one. Geo

The part that I'm thinking is causing the problem can be removed without taking the carb off or apart. If you have a large black plastic idle speed screw, you can back it all the way out and underneath the head of it is another black plastic piece stuck down into the carb. Pull it out with needle nose pliers and there is a tiny hole in the end of it. It is very tiny and clogs easily. Use a thin strand of wire to poke through it and clear it out. Sometimes the tiny o-ring on it needs to be replaced too. It is a 4mm X 1mm if I recall correctly, so you can get one at a parts store and not have to buy a whole carb kit to get one. Pop it back in place, add some seafoam to the gas, and see if that solved the problem.

I had time today to look close at the unit.

I took some pictures also. Will try to upload.

The generator runs great when you jump it.

When you turn on the auto throttle it shuts down.

It seems that the carb is ok, but out of adjustment when the auto throttle arm pushes or engages.

Once the generator runs for several minutes you can turn it off and then turn it one and pull the starter rope and it starts.

If it sets a while (off) you can not start it with the pull rope for love or money.

The plunger at the bottom is what pushes against the lever arm going to the carb when the Auto throttle is turned on.
