SOURCE: Need more amperage from generator.

No! The two receptacles are already connected together where they take power from the generator. Two are provided so that you can plug in two items, but the total power must not exceed the rating of the generator.

It's either not getting enough fuel, or the govenor is not working. When the engine is running, watch the throttle linkage between the carburetor and engine, looks like a bent wire. When you throw a load on it, it should move to give the engine more power, if it dont, try moving it by hand.
If that appears to be working ok, check the fuel line from the tank to the carb for good gas flow.
You can also remove the float bowl on the bottom of the carb, it's a round bowl on the bottom of the carb with a bolt in the middle of it...clean it out and check the float. The float looks like a little catamaran, make sure it is moving freely up and down. That is about all you can do without removing and cleaning the jets in the carb.

Good luck, & i hope this helps.

Greetings. I have a eu2000 honda inverter with the following problem. The high generator runs too fast, when the idle is activated, slows down a bit, but does not increase


on the governor control back to the carby , there is a screw that adjusts the spring tension for the governor arm
that screw is the adjustment for engine operating rpm not the idle screw

Honda eb5000 generator starts fine seems to run good but idle control does not work . will not rev up at all.i can turn carb idle screw in to bring revs up it makes power out of the generator but idle


Like a lot of stationary engines a generator engine is governed, or at least should be governed.

That is to say, when the engine is started it should be running at a predetermined speed which is not an idle speed but the speed the engine works most efficiently and that typically would be in the region of perhaps 1800 to 2500 rpm. In the case of an alternating current (ac) generator the speed will be determined by the alternator and the requirement of the frequency of the ac output to be around 50 to 60 cycles per second.

It is the function of the governer to maintain that preset speed within fairly close limits so when an appliance is connected to the generator and switched on the load increases and if it were not for the governer the engine would slow down which would be unacceptable. The governer therefore opens the throttle and restores the speed to the preset value. When the extra load is removed the engine will speed up momentarily and then restabilise at the right speed.

The governer is somethimes an engine driven set of bob-weights hidden inside the crankcase and sometimes nothing more complicated than a flap moving against a spring in the blast of cooling air from the fan. In all cases the governer is connected to the carburettor, typically by an adjustable link that includes a spring.

From your description it would seem the governer of your generator engine is jammed, broken, seriously maladjusted or simply no longer connected.

I hope this helps.

Have continually to increase speed to maintain voltage


Check the idle-stop screw. They tend to back out, causing the generator to slow down and not maintain regulation

The tines on a honda f220 always spin and don't change speed when clutch is engaged but speed up when throttle is increased. Adjusted cable with no luck.


I believe that unit utilizes a centrifical clutch. try decreasing the idle speed and see if the tines stop. They should then engage as throttle is increased.

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.

Honda 5HP pressure washer. When you press handle to get pressured water, motor does not rev up to give you high pressure.


Most small pressure washers do not have an automatic throttle control to increase engine speed on demand (activated by trigger on wand). You must set the governor/throttle to about max. to get the rated pressure. A honda motor produces 5 hp when it is turning about 3600 rpm. To increase the life of the pump, use about 80 % of capacity of the pump and increase only for stubborn debris.

My EF2400iS surges under low loads. Seems to smooth out with larger load. Any suggestions? Throttle motor or control box?


Idle speed screw may need adjusting slightly to increase idle speed. Also Main jet and Idle mixture Screws may also be out of adjustment

I have a honda engine gx620 coupled with my generator and in tern connected through a power center to charge batteries and sync with my inverter. It's showing only 60hz dropping to 59hz and I need to know...


You did not mention how many amps your system is producing/drawing, however I don't think that you need to adjust the governor. Your engine can produce 18 hp at 3600 rpm. At 3600 rpm your generator is producing 60hz or cycles. As the load increases /decreases it has an effect on the governor thus the change in cycles. If the load increases past the capacity of the engine, the cycles will drop. To stabilize, reduce the load. 59hz is produced when the engine is turning about 3550 rpm. If you increase the speed of the engine to compensate cycles may increase past 60hz. 3650rpm will probably produce 61hz. Engine speed could be fluctuating due to other reasons (vacuum leak, dirty air filter, plug, etc ) if there is only a small load on the engine/generator. If you would still like to adjust the governor please email the load on the generator and I will help with instructions. Good Luck with your generator it is a very nice unit and built to last.
