should eco-throttle always be on?

..."...Eco-throttle (load-dependant speed-control-type electronic governor)
This load-dependent speed-control-type electronic governor automatically controls
engine speed to best fit load. This allows for effective engine control when supplying
power to equipment requiring large amounts of electric power upon start-up..."...
all series from the 2000i to em5000i and eu6500is have this feature.
question is, should it always be in the "on" switch position and is there any
advantage/disadvantage if it is "on" and large starting loads are cycling?

Turning the eco-throttle off will help the generator handle larger
starting loads. Unfortunately, turning it off also throws away most of the
advantages of the inverter technology, because the engine will be running at
max RPM continuously.
Just as hybrid vehicle technology delivers its greatest advantages in city
stop-and-go traffic, generator inverter technology delivers its greatest
advantages with modest loads. If you are planning on continuously running
heavy loads, buy a conventional generator.

I tested a couple conventional generators and they did not maintain 120/240 volts but
the honda inverter did

In my experience with these critters you rarely need to turn Eco Throttle
off, only when you have a load that is hard to start. Of course, if it's
that hard to start then it will probably have trouble running it anyway.
With this design if the inverter is overloaded it will shut down and you
have to turn of the generator and restart it to reset it. I agree with
Vaughn that in cases such as these you are probably better off with a
conventional generator.

What those guys said but its not a bad idea to run with it off during
maintenance.
When you change oil you should use power foam or similar cleaner to help
stop buildup on the valves. THen I run w/out eco throttle and shoot that
stuff in the air intake.
Give it the old italian tune up from time to time but otherwise yeah use
the ECO throttle all the time unless the start surge fails on a big
device

Define "maintain 120/240 volts". I suspect that you are expecting an
excessively tight tolerance from a small genset, probably tighter than
the tolerances allowed for utilities.

115v on both legs, using conventional generator, 123v on both legs, using
honda inverter

Either that, or you completely misunderstand what "eco-throttle" is
designed to do on a conventional generator.
"Eco-throttle" on a conventional generator is designed only to reduce
fuel consumption when there is *no* load on the generator as in a
construction site running saws and the like. This is different from how
"eco-throttle" works on an inverter generator.
On conventional generators "eco-throttle" is designed to bring the
engine back up to normal RPM as soon as a load is applied, and these
generators do not supply the normal voltage or frequency when in idle
mode. This is not a problem at all for the applications they are
designed for, a circular saw does not care at all if the voltage and
frequency are out of spec for a half second when they are first turned
on.
If you put one of these conventional generators in "eco-throttle" mode
and hooked up just a voltmeter (no load) you would no see the 120/240V
or 60Hz you expect and this is *normal*, not a fault in the generator.
There will be some minimum pickup current to trigger the normal idle, so
a very small load like a single light might not trip it. If you read the
instructions for one of these generators, they are pretty clear as to
what the "eco-throttle" mode is designed for.

define 'during maintenance'. do you mean the time interval like 50 hours
runtime and approaching it?

I was going to use seafoam as fuel additive

ketchup, spaghetti and vino ? or something on the style of berlusconi ?

1kW of power was running/needed and the conventional gen was rated at 6600
watts runtime power
Pete C.
115V is entirely within normal tolerances, including those for
utilities, +/-10% is considered normal for most utilities, i.e. 108-132.

Like during oil changes. Whenever the manual suggests (I do it once a
month but I run all the damn time so ..)

My brother loves that stuff. I haven't used it on a honda.
The guys at honda told me to use amsoil power foam and shoot that into
the air intake with the eco throttle off. I guess they had seen a lot of
build up on valves etc, especially running eco throttle and low loads.
The generator does just fine at low speed, but if you run it ALL THE TIME
at low RPM it can get a little build up. The power foam and like 10 mins
at full throttle whenever you change oil helps keep that to a minimum.

LOL
THe italian tune up is to take your car/engine and run it like you stole
it. Engines need a little time at high RPM to burn out carbon or
whatnot. Especially alpha romeos -- granny going to church every sunday
in her guiletta can make a very rough running car after a while. Peg it
once in a while !!
