I don't know of any wiring diagram for these. Some one else may have something. I didn't get pics when I pulled the flywheel to check the stator. At the time, I didn't realize there was no paperwork on these systems. The trigger module is just under the flywheel shroud.

So thats where the tin can cut in? I need to take off the shroud anyways.

You'll see the trigger right there once the shroud is off. I'm not saying that is your problem, but worth looking into. Helps you understand the system too. You probably have a 10 amp stator in there too.

This morning I went out to the 1450 to try and get it running and I noticed that the ignition coil wire was off. Nope! Broke off the whole dang tab! :mad2: Looks like now I'm going to convert to points unless anyone has a good way to fix it.

Now you know where the issue was. Is it the coil wire broken off, or the wire from the trigger?

the wire that goes to the coil the tab on the ignition coil is broke off. This problem wasnt there when I got it but I figure if I leaned over I might have caught it and bent it

I was thinking of soldering it a little bit. Just have to do a little at a time so I dont over heat it.

Well this morning I had spark. I was so excited so I sprayed in some starting fluid and nothing happened. Then it popped once and that was it. I took off the head and the exhaust valve is stuck open. Oh yay me :wallbanging:

Put some lube on the stem and see if you can tap it down a little!

Ok right now it's soaking with some MM oil on it. I noticed that the side of the piston that faces the valves looks a little worn down on the side (I can see the top ring) so I figure I might as well rebuild it. Put new piston, rod, and valve train in it

If the piston is that bad, you may as well.

Is it common for these K321 to wear down pistons on the side closest to the valves? This is the third engine I've gotten like this. Thanks

That I haven't a clue on. I only have one and it looked pretty good when I did the head gasket.

All engines wear the piston and bore more on the thrust side of the cylinder.  The thrust side is always the side of the bore that is counter to engine rotation, thus the valve side on a Kohler.  This is phenomenon is common to all engines, whether single cylinder, multi-cylinder, or any number V configuration.
