Been thinking, with the drive pulleys set up to operate the engine at 3000 RPM’s the Kubota engine should pull a 3500 watt load.
On my EB300 engine, the rating is 6hp at 2600 RPM. It will put out 2500 watt continuous and 3000 watt intermittent. How long? I don’t know. It’s in hours. The surge capability is very good. It just handled over a 50 amp momentarily surge last week. The generator has no problem starting a 1.5kw nail gun compressor with the air tank having 120 psi pressure during startup. The engine handled it easily.
Your EA330 should exceed the EB300 rating with ease. My guess is it should handle a 3000 watt continuous load with a proper cooling system. And a 3500 watt load intermittent for an hour or more at a time.
The EA300 & EA330 Kubota engines put out almost the same hp. and torque. It’s so close that it makes no difference which one a person has.
Over ten years ago while I was talking to a Kubota application engineer and I ask, why Kubota increased the bore on the EA330? His answer was, to help the engine meet new tier emission standards.
They also got rid of the jet start device that aides startup in extreme cold weather. My guess is when the device is used on startup and once the engine fires up there will be a white cloud lingering in the air until the extra fuel that was injected in the intake is used up. It’s too bad the jet start device was removed because that extra fuel definitely made a difference in cold weather. Especially if you had a dead battery and the glow plug was inoperable. I’ve used the jet start regularly on the EB300 build and the engine usually fired up the first or second try.
In my opinion, the Kubota EA, EB and EL series engines are great little engines.
