Is a slight generator surging normal?

Hey guys. Last weekend we slept on the hook for the first time in our new to us Mainship 31. The PO never ran the generator and Iíve had issues with it because of it. All it needed was a fuel pump and new plugs. Now she starts up and runs great. We probably ran it for 12 hrs and it ran both ACís through the night and then one AC and one stove the next morning.

Anyway, the only thing is when an ac unit kicks on, it obviously loads the generator. It would bog under the load, then recover, but it sounded like the governor was overshooting then undershooting. It would cause the engine to surge a few times before calming down.

Before I start chasing things, I wanted to see if thatís normal or not.

Itís a gas Kohlr 7.5 genset.

Iím tbinking about running a tank of Lucas fuel injector through it. I want to do that for the mains anyway.

Since I know itís going to come up, I did a ton of research about running the generator while sleeping and I determined ours to be safe. Itís located outside the main cabin and we have two brand new battery powered Co2 detectors that I tested right before bed.

Thanks for any help.
