| Maybe something to check....
When I 1st got my Milbanks, when there was no or little load, like in test run mode, it would surge in RPM, like a lot,...... up, down, up, down.
After a lot of checking, it ended up factory forgot to install a small baffle between the engine and the outer case where the intake air was brought in. Anyhow what it did was mess up the sensor that read what the barometric pressure was, this controlled / changed the fuel regulator to the engine, thus changing the fuel mixture for it to run correctly.
It took me and the technician quite a while to figure it out.
Under full load, it ran like a dream.
Maybe you could have a faulty sensor ?? or connection ??? if so equipped.
Hope this helps.
