Default Kohler 14 HP Not Getting Spark

I bought this old golf cart for $60 the other day. It came woth a spare engine block, new magneto, and a John Deere 318. The golf cart has a Kohler 14 HP horizontal shaft engine. I tried to start it but it has no spark. I put on the new coil and still no spark. I replace the thing that goes in the little black box on the bottom of the block side and still no spark. Why do I have no spark? How is this supposed to be wired up? There is 2 wires coming off the negative side and 1 wire coming off the positive side. Thanks in advance

Is there a black wire running down the the throttle assembly on the motor? If so you will have to open the throttle to get spark. Other then that sounds like kill wire is bad or shorted out on the motor maybe?

I dont remember seeing a wire around the throttle assembly. I was thinking that maybe the wired got chewed by rats

that thing down under the black cover...is your points, their gap has to be set properly using feeler gauges, best to download a manual and look up "breaker points adjustment"...

Your model number is K321

There is only one wire to the points. It must be isolated from the battery/block ground when they are open and then they connect that wire to ground when they are closed. (Test for a short circuit or to see if they are faulty) While the points are closed, it energizes the primary coil winding. Spark happens when the points open and the condenser which is mounted adjacent to your coil and wired to the coil's neg (-) terminal cause the primary coil winding to transfer energy to the secondary winding which makes your spark plug spark.

The point setting is .020" BTW--> the points need to be CLEAN for them to work. Remove and inspect the faces to verify. Here's the Service manual if you don't already have it: http://www.mytractorforum.com/showthread.php?t=61904

For a short while I was getting spark whenever I turned the key on but that was it. I dont think my "new" coil is actually new. How much is a new coil, points, and condensor?

Sounds like dirty points, the points sound like they arent opening or are stuck open...and they arent letting the coil release.

Seriously...clean the points, set the gap.

I'd say the points to, after sitting for awhile the points stick or need to be cleaned with a file, ( a double sided finger nail file will work.

I havent had much time to work on it but when I get some free time I will clean the points and hopefully get this thing running. Does anybody know who might have made this utility golf cart?

I had a little time today to work on it so I cleaned the points but still got nothing. So I took off the cover to that little box where the points are and spun the engine over and noticed that little push rod is not moving. How can I fix this?

If the push rod is not moving it could be a couple of things. The easiest would be that the push rod has worn down so it is no longer the correct length. If that is the case buy a new one and set the point gap at .020 with the points at their widest. If a new one doesn't make it work or move then you have a broken camshaft and probably some internal engine problems. Pray it is a worn push rod. Roger

I have another Kohler 14 HP laying around that has the same problem. Both push rods are the same length.

It doesnt move it much, only about 1/2 the thickness of a spark plug gap...so its barely visible. With the points removed, if you put the push rod in and hold it with your finger, and role the engine 2 turns, you should feel a "bump"...
