The Kohler K241 on my new to me Cub Cadet has no spark, been trying things, no luck yet... I have seen this topic before, but not sure.

Have you already checked the points? Power to the coil?

Try using a different wire to the points and coil off the battery and direct connect without the key switch, if nothing then a different capacitor, these things are usually a connection issue or bad wire/switch.

Been filing points and swapped condenser and then shocked myself... No visible spark, and no offers of running.

Change the spark plug.

That could be it. Change spark plug as trowel says. Noel

I had a Kohler K that drove me nuts that way. I used a multi meter to check for continuity and found that one of the wires on the coil had a terminal that was tarnished. I cleaned it with sand paper and all was good. It doesn't take much to mess up your circuits.

Do you have 12 volts going to the coil?

Lots of pieces to the puzzle suggested here..

 

To make spark on one of these you need:

 

At least 10.5 VDC to the Positive side of the coil.

Negative side of coil hooks to both the points and the Condenser  (2 wires -Condenser needs to be grounded/ mounted to the engine BTW)

 

Crankshaft set to TDC on the compression stroke and point gap set to .020".  Verify that the moving side of the points is not somehow connected to ground when points are open.  *Some continuity through condenser but not a lot.  

 

The fact that you shocked yourself tells me you have spark but it's bleeding somewhere else besides the plug..  Is the plug wire damaged or grounded somewhere?

 

**Points should open and close as the engine spins or Cam troubles..

 

Spark plug needs to be hooked up and grounded to the engine to test or use in-line spark checker.

 

Try to reduce the plug gap and recheck if still no spark seen.  

 

OR you can read the book and follow the steps in section 8 to check out the system and replace the right part..

 

Just saying..

As it sits it has a known good spark plug, plug wire, new condenser, filed and gapped points. We see no spark at the plug but the points look like a fireworks show. Any opinions?

No output from the coil, interesting. I dare say the coil itself is shot unless the plug wire is broken internally, try changing the wire, if nothing then it's the coil itself.
