Customer Question
I have a Kohler...

I have a Kohler Model #M18GS, Spec. #24552, Ser. #1704305016. It has been converted to propane. When I try to start it., I get a "Over Speed" light and it dies

Mechanic's Assistant: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?

What should I look for to correct or fix it?

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

If I can.

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

Where to go for a service manual. Nothing else at this time

Hello, my name is ***** ***** I am going to assist you with this.

What are the brand, model and serial number of the genset itself?

Ask Your Own Small Engine Question
Customer reply replied 8 months ago
All of the information is in my original question. The generator itself is a Power Guard with remote and local start. I get "Over Speed" on the local start switch.My question is why do I have a "Over Speed" light notification? Is this problem associated with the Gen controls?
Where can I get a repair manual for this Kohler engine?
Customer reply replied 8 months ago
I don't have the information on the generator itself.
Technician: Hank F., Technician replied 8 months ago

The numbers you gave me are for the engine - they do me no good.

I have to know the information about the genset.

The over speed is a function of the genset control, not the engine. If I don't know which genset this is, I can't help.

I will get it by one week from Monday. The Gen set is at my home in the Mts. It is a 4hr drive from here and I have to work this week. Sorry to put you thru all of this.

That is no problem at all. I am used to having to wait.

A lot of people aren't allowed to store their RVs or boat at their homes, or don't have room for them, so when they have a genset issue, it may take them a while to get to it.

I also get cussed out a lot, and get called childish names - and I thank you for not putting me through that.

No problem. I've had my share of childish responses over some trivial matters. Service Techs are born with broad shoulders.

That is a unit made by Baldor, and I have nothing on it at all.

I am going to have to opt out of this one, and let someone else take it. Sorry.
