Happy New Year. Mechanic's...

Happy New Year.

Mechanic's Assistant: Thanks. Same to you!

I own a generac model(###) ###-####10KW Propane power.

Mechanic's Assistant: I'll do all I can to help. How long have you been dealing with this?

Has recently been running high rpms then down till it feels like it wants to shut down then picks up again and so on for a while and then runs smoothly for a while and so on .I have noticed that sometimes I add load to it will help it smooth out but I believe there has to be something wrong .

Mechanic's Assistant: Do you plan on doing the work yourself?

If i can,Yes

Mechanic's Assistant: Anything else we should know to help you best?

Cant think of anything

Hello Hank.

Ok, we can pretty much rule out a weather issue.

The revving up and down is called surging. It is usually caused by a lack of fuel getting to the engine.

The first thing you need to do is to have the fuel system of the genset pressure tested.

Unless you have had gaseous fuel training, and have the proper equipment, this is not something you can do yourself.

There is a possibility that your demand regulator has gone bad.
