Question about Honda 3000 Watt Portable Generator

Honda 30is generator

I just had my honda 30is generator serviced and it is running a little rough when the eco trottle is on (or in the eco position). It sounds like it is starving for fuel. Is their any adjustments on the carby or anywhere else that may help or do you have any other suggestions? It was running fine before I got the service done. If I run it in the off position so it gets full power it runs better but you can still hesr it missing.

SOURCE: 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.

SOURCE: my 13hp honda generator won't run.I have cleaned

You cleaned the fuel bowl? Was there any dirt, etc, in it? How does the fuel line look? How about the bottom of the fuel tank? How old is the fuel?

From your description, it 'sounds' like a fuel system problem. If it's a Honda EU3000is, it has Electronic Ignition, and electronic ignition usually just goes out all the way, not slowly.

The fuel line is small, and easily obstructed. Does fuel flow when the fuel line is removed from the carburetor? After the generator starts, runs, then dies, remove the float bowl. How much gas is present?

Observe the float. See if it's in good repair.
Check the float needle. See if the rubber (Neoprene) tip is squished, or is still in good shape.
Could be that when gas fills the float bowl, the float raises, then gets stuck in the up position, cutting off the gas flow.

The generator will not hold the load.

Confirm that the ECO-Throttle Switch is in the off position. When in the ECO mode the unit goes into an idle condition and when detecting a load will spin up to operate the load.

In the off position the unit will remain in the ready for load speed taking the initial load with less hesitation.

If this does not solve the problem it is likely the carburetor has some old fuel residue. This residue restricts the fuel flowing through the carburetor. Suggest using a fuel additive carburetor cleaner added to fresh fuel and allow the unit to run under load for an extended period. These gas treatment products are readily available at any auto parts store.

These carburetors have no adjustment for fuel mix and after trying fresh fuel and cleaning the fuel system with additive the only remaining choice would be cleaning or replacing the carburetor.

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.

I purchased a Propane Generator from Central Maine Diesel a few years ago.

20 HP Honda engine, Italian generator head.
Paid about $2300 plus shipping via Paradise Freight which was a few hundred.
I see the price is just a bit higher now... But the one I want most is Yuchai which i saw from a website.

Recently it blew a capacitor. Central Maine sent me 2 for the price of one even though it is out of warranty. $39 total for two.

I looked at generators on island but a similar Honda at Quality electric was close to $6000 and it wasn't even a 13750kw. More like 8 or 9000kw if I remember right.....

They have many generators at great prices but this is the one I settled for.

However, it is said that the Cummins generator is more popular than others.

Rough running engine, air intake seem to be involved. what should I be checking?

should your vehicle by any chance be a V6 then you should have the trottle positioning sensor checked as this is the commen cause for a rough engine
