On the eco switch the generator is supposed to drop to an idle when no current is being drawn but rev up to full power when there is a draw. As to regular when the generator runs at full power to supply full power all the time.
I would say to check if it is running rough and hunting while at its lowest idle firstly
How old is the
fuel. If your petrol is older than a month or two it could
well be off. With the higher hydrocarbon activity in petrol it goes off quickly. Empty the
fuel tank and empty the
fuel bowl on the carburetor. (the carburetor can be emptied usually with a screwdriver inserted to the bottom of the
fuel bowl and undo a screw to allow the
fuel to drain out - do it outside or refer to you instruction manual)
Refill with fresh
fuel from garage station - normal unleaded or higher.
Next check the spark plug has not been contaminated with lots of unburnt carbon from the older
fuel. Take it out and clean preferably with a bronze brush - you can get bronze brushes at any auto
shop.
If it is still hunting and running rough you might have some
debris in the carburetor. If you are mechanically minded you could pull it apart and clean the parts up in clean petrol or methylated spirits.
Other than that it might need a retune - should send it into the
shop but you could have a go if a
shop is not handy. They really only have a screw for revs and a screw for fuel/air mixture. Everything else is set. To much or too little of either and it will hunt and run rough.
Last thing is to check the oil. They do have an oil cut out switch for low oil but it would only try to start and then shut down if that was being active.
Hope it helps

Stale
fuel is a HUGE problem in small engines
Our local small engine repair
shop told me that 3/4 of the engine repairs he does is caused by
fuel that has gone off. In particular ethanol fuels.

One thing I forgot to mention to check - the air filter. If the air filter has become blocked as often happens when running gen sets at ground level they can change the air
fuel mixture. Just take out the filter foam - clean in detergent
water or replace. If you wash it make sure it is very dry before use.
