Does the yamaha EF1000is inverter generator 1kva


it seems to be the standard that the rating or model ??1000 or ??1500 or ??2500 or ??5000 or??5500 or ??6500 is the kv rating of the gen-set regardless of straight or inverter
so if yours is EF1000 it will be 1000 watts or 1 kv
remember that most electric drills are 1000 watt units so a unit this small is mostly good for lights, charging batteries, small compressors for tyres

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

Yamaha EF1000is, Will no run without choke on


It is starved for fuel. PROBABLY needs to have carbureator cleaned and adjusted OR the fuel filter may be clogged.

Running at idle speed


1) Check the "Economy Throttle" setting (or some similar verbage). Inverter types dont have to run full speed to produce full voltage.

2) Apply a load. These magically accellerate and decellerate according to load conditions.

Hope this helps,

Yamaha EF1000 Will only idle and produce 12VAC


My guess would be that some failsafe is in action here. It is possible that either a fuse OR the breaker is bad, or is not resetting in the case of the breaker button. Yamaha likes to idiot proof these things. Some of them disable the sparkplug if the oil gets low. Forget about just a warning light.

Yamaha ef1000 will only idle and produce 12 vac


Hi, I have the same generator and I pull the load and it is fine. The engine RPM is controlled by the 
governor. The voltage will not come up until the RPM is at full. First see what the RPM problem is and then check the voltage. Open the cover and look to see if the carb linkage is hooked up , if it is you mite have carb problem and address that first. Hope that helps.

Not sure exactly what you mean but here is what I know:

1 - You shouldn't have to use any choke at all once the engine has started and warmed up, if you have to apply some choke to get the engine to run correctly then you have a carb problem. Clean and service the carb and see if that makes it all better.

2 - The idle speed is set by a small screw on the body of the carb itself, if it's set too low the engine can shut off rather than idle. Make small adjustments until you get it right.

3 - Dirty air cleaners can cause problems with idle

4 - fouled and/or misgapped spark plugs can cause idle problems
