Honda EU3000iS Inverter Generator Questions & Answers
Does the honda eu3000is have a compression release and where is it if it does
I do not believe so. In the shop manual there is reference to a decompressor spring (Part #7 if you look up an exploded view of the camshaft on a site like boats.net) which is attached to a small weight on the back of the gear on the camshaft, but it sure doesn't look like it would do anything to release the compression within the cylinder.
Generator is using oil and blowing white smoke. How do I find the vent that is plugged?
I don't know of any other "vent" in that engine other than the breather tube that goes from the head cover to the air cleaner. If there is excessive oil being sucked through that and in through the carburetor, I guess I would wonder about compression getting past the rings causing excessive crankcase pressure. The only other way for oil to get into the combustion chamber and into the exhaust would be through the valve guides. Of them, the exhaust valve guide is generally the one that wears first.
Generator burning my electronics up
take you generator in and have the output tested for correct voltage and sine wave configuration
electronics rely on a perfect sine wave ac current as a manufactured sine wave affects electronic components such as capacitors, transistors and diodes
generator sets that run an alternator ( not an inverter ) have a pure sine wave and have less affect on electronics.
go google and type in search headings like ---sine wave, inverter sine wave, sine wave affects on electronics, alternator operation and inverter operations and then you may get a pointer as to why your inverter gen set is affecting your electronics
Generator won't start anymore, barely pushes any power the one time it did.
Check you have put enough oil in to correct level , and that there are no leaks from oil drain plug.
Changing the oil every 4 weeks seems a bit excessive and you may have caused the sump oil plug to leak as a result ,this is from the Honda specs on this model .
Oil alertâ„¢
This is a useful function that prevents damage to your engine by automatically shutting the unit down if oil drops below a safe operating level.
As far as pushing out less power check your generator bushes and rotor com they may be dirty, other than that it may just require a good service from a Honda dealer . Checking the spark plug for erosion or dirt may also help .
Honda 3000is runs great on eco but hesitates and either stops the load source or stops running itself when under load.
Sounds like the throttle control motor is not adjusting the engine speed to compensate for the load. Does the generator rev up to full speed if you turn OFF eco with NO load?Funny thing, I have one on my workbench that is doing pretty much the same thing. Runs on eco, revs up with eco off with no load, coughs, sputters and dies with a load in either mode. I will update with what I find when I figure it out in the next week or so. Have a new carb on order.I swapped the carb and it made no difference. Still backfiring (rather dramatically) and won't stay running. I see on some other posts that Valve lash will cause this. It makes total sense as the exhaust valve gap actually tightens as the engine wears which would keep the exhaust valve slightly open when it ain't supposed to be allowing raw fuel to enter the muffler.With this one I can believe it as it has a ton of hours on it and I know they have never been adjusted.I will try to get a chance to do it over the weekend and update this post when I do.
What is the proper procedure for adjusting the intake and exhaust vales
You have to pull the rear (muffler end) cover, rear muffler protector (the metal vent), the rear handle, the lower end plate, and the fiber muffler protector so you have access to the head cover. Remove the head cover, disconnecting the breather tube as you do it.
Turn the engine (using pull handle) to top dead center compression (both valves fully closed). Use feeler gauge to check the valve clearance between the rocker arm and the valve stem.
Intake should be .15mm +/- .02mm (.006in +/- .001)
Exhaust should be .20mm +/- .02mm (.008in +/- .001)
Adjust as needed by loosening the rocker arm pivot locking nut and adjusting the rocker arm pivot. Tighten the locking nut once set.
Put it all back together. :)
Will not crank.
If you have spark and gas to the carb might check to make sure there is oil in it
No spark
The grounding wire that grounds the engine frame to the negative side of the battery may have broken off where it connects to the block. You have to take the red metal shell off to get to it. You can easily check this with a piece of wire ( I used one wire from a set of jumper cables). Clip one end to the grounding lug on the side of the generator, and the other to a bolt on the engine block. See if it starts. If it does, you need to fix the grounding connection. I used one of the braided ground straps that you can get at an auto parts store.
The engine/generator assembly sits in there on rubber motor mounts, so it needs to have a way for the ignition to be grounded.
Overload light eu3000 comes on with trailer roof ac never did before
The battery is really only there for the electric start. Put a digital volt meter on it while running it under the load of the AC unit. Or if it goes off on the overload with the AC unit, try a variable load like an electric heater or two that you can switch on in steps. Most space heaters or hair dryers have a 1000w, 1250w 1500w so you can increase the load. Watch what the voltage does. If at 1500-2500 watt load the voltage starts to drop drastically, say from 125v down to 90 or 80v as the load increases, that usually indicates a problem with it not getting enough fuel. On these inverter generators, the carburetor is controlled by the inverter by the use of a throttle motor. As the inverter senses the demand for more power, it increases the throttle to deliver more horse power of the engine, thus meeting the demand for more electrical power out.
I have seen a couple things cause this. A partially plugged jet in the carburetor can cause it. A bad throttle motor (Part# 21) on the top of the carb can go bad. I even had one that I caused myself by not putting the little spring (part #20 on the exploded view of the carb) that sits under the throttle motor in correctly.
Why does it start with the key when cold put not when its hot put i can pull start it with one pull?
You may have a cylinder head gasket problem either that or if this is a two stroke engine crank case pressure is critical, once hot there may be a pressure leak not enough to stop it from running once started but enough to stop you starting when warm, alternately a fuel evaporation problem not getting to pot before evaporating due to heat or blocked fuel jet when warm, if this unit has a choke is it disengaging a warm choked engine rarely starts and floods out smell of petrol will be high.
check that plug is not breaking down under pressure try another one check plug gap when warm it varies. hope this helps
