Generator governor issue

[wap13]

I have a briggs powered devilbiss branded generator rated a 4k continuous, 5k surge.

It cranks and runs great but when placed under a load it does not idle up, it lugs slightly when placed under load. I would like to think this is an adjustment issue but I am not well versed in generators, or small engines in general. I am much more comfortable with truck and tractor size engines.

Any input is much appreciated. I can get more pics if needed.

Thanks

No experience with that type. A guess is that it runs static RPM and is not set high enough. If it has an idle down switch for intermittant power need there should be some sort of controlling solenoid that is not doing it's job. I generally dislike how B&S goes about linkages and such. If you have a multi meter you can set the RPM by reading +\- 60hz at 120 output socket.

Thanks for that. Did not consider setting it to 60hz. It has to be 30 years old and obviously not a high end unit. I had not considered it would run static RPM as my honda adjusts rpm to load.

The only wiring I can find is for the ON/OFF switch and that ties into the low oil shut down. So likely static, Thanks again.
