Kohler engine

I have a Kohler gas motor on a comperssor, it's a single cylinder motor. The tag is off the motor. Anyone have any idea how I can find the model of the
motor. The motor is around 20 years old. Thanks, Stan

Should be if older flat head , the ks have the number cast into the block just above the crankshaft
Example .
K241,K301,K321,andK341.
Im not familiar with the smaller Kohler sizes or I would include them
This is one way to tell what you got
Another thing is the k301 thru the k341 all have the same stroke crankshaft .just bore is different . Some larger crank cu in have counter ballenced crankshaft?
The other way is the tag on the fan shroud ,but shroud can be swapped out in repairs

Assuming it is a K series a good starting point would be to count the cylinder head bolts.

7 bolts = K 161, K 181

9 bolts = K241, K301, K 321

10 bolts = K341

If you go to the Kohler website they have all the service and owner manuals free to download.

The service manual covers all the K series and is a very good detailed source for about any information you may want or need.

What part are you looking for?
Many parts are interchangeable.

rings, and gaskets for now. Stan

One further caution: some times a K301 casting was bored to K241 size.

Everyone assumes it is a K series. If it is only 20 years old it would more likely be either a Magnum or a Command. Is it overhead valve?

A picture would sure help.
