Question about Honda 3000 Watt Portable Generator

1 Answer

I have a brand new honda 3000is generator. I accidently added too much oil and gas. (I filled according to the capacity in the manual, however both the oil and fuel overflowed while filling). I cleaned the mess and the generator ran but smoked profusely. After draining some of the fuel and oil. It will not start at all. Did I damage it or is there something I need to do to make it work now?

    hey mike,

    Thanks for the your response. Yes, I overfilled both the oil and gas separately. I do not have access to my manual. Are there any online resources about where to find the spark plug and how to remove it?

Hi there,

If I remember correctly this model does not use a fuel/oil mix. Please confirm this.

If what you are saying is that in filling the device with gas and checking the oil level, both overflowed, then we are good.

As you have done, drain both to their proper levels.

Now pull the spark plugs, they are most likely fouled with oil.

Turn the generator over a few times to clear the cylinder of excess oil.

Give the plugs a good cleaning. You may need to replace them. I just have a thing about tossing something with life still left in it.

Put the plugs back in and fire it up.

Best regards

    Make sure that the oil level is full to the point of overflowing from the filler hole. The engine will not run if it is even slightly less than full of oil. Look at the oil alert LED while you turn the key to start it, is it lighting up at all? If so, add oil to the point where it starts to overflow when the generator is sitting on level ground.

Honda generator wont start it was running fine.

If you filled the fuel tank with gasoline enhanced with ethanol the fuel may be bad and caused the carburetor to gum up. Also Honda engines have a low oil sensor and from your description of the oil, can cause problems with the sensor and the engine won't start. Try changing the oil first and then adding a small engine gasoline additive that helps with stale gasoline starting problems.

I have a 3000is not starting. Has gas spark oil.

Use fresh gas! Dont just pour some on top of the old...Change it out.

Drain the carb bowl (Honda carbs have a drain screw slightly off-center of the bowl bottom).

The Honda EU3000is uses a vaccuum-operated fuel pump and old gas will ruin it also.

Take the fuel supply line off the carb inlet, direct it in a container and spin the engine over. It should pump a stream that is FULL LINE DIAMETER.

If still no start, take it to an AUTHORIZED Honda Power Equipment Dealership.
Find one here.

Hope this helps.

95 Honda Accord a/c blows hot air.

You should have added red died gas to your AC to see where it leaks, then fix the leak, then recharged it properly.

Battery in a honda 3000is

The battery is behind one of the end plastic casing pieces. You have to remove the center plastic panel, then remove the bolts holding the handle in place, and then remove the small, lower metal panel. I don't remember if it is on the side where the exhaust opening is or not, I believe it is on that same side.

My trace inverter SW2512 will only allow pass through power.

First problem is caused by the new generator producing too high a frequency... 65 Hertz is above the inverter limit. Adjust the governor down to 60 or 61 Hertz.
Breaker tripping may be due to excessive current draw from the Honda. Check the max AC input menu on the inverter. It might have been set lower to avoid overloading the original generator but if DC power was turned off at any time while you were changing generators, the inverter would have returned to it's default settings which may exceed the Honda's capacity.
