I have worked for dealerships in my past and been part of equipment "upgrades" and even spent time in training for new machines. IH combines specifically.

When a company like Kohler finds a problem with their product, there several ways to deal with it.

They can:
Let the dealer deal with the issue.
Incite a recall.
Or put out a service bulletin on it.

Being that the original manual says to shut it off from a low idle setting, and then a supplement was added saying to shut it off from mid throttle, my guess is Kohler knew some engines had issues with dieseling. Instead of calling in a bunch of motors for a "non major" issue at a HUGE expense to Kohler. They instead found out that running the engine at a little higher idle gave the engine enough velocity to burn off the fuel still coming into the engine as the fuel cut-off did it's job. Too much of a lag time, too hot on engine, idle set too fast...... whatever the issue, Kohler didn't care because it cost far less to print a couple million one page supplements than it did to fix the issue. It pleased the customer, the complaints went away..... problem solved. Can it be fixed? I'm convinced it can. I am also as deeply convinced that Kohler didn't want to spend the money on 1 million customers complaints when they could just tell them to shut it off at a little higher throttle setting and it worked. Just my theory, and IMHO it fits the bill well.

See, now THAT makes sense!

Bravo guys!
Excellent conclusion. I really thing John hit it near the bullseye with his final explanation. Remember, just because it's OEM doesn't mean it's right or even the best way to do it. You would think that a company as old as GM could make a car with an ignition switch that would work. Oh well, you could always just let it run out of gas, that would stop it. LOL!

Thanks for your input and dilligence today, J! I learned something!

My 1864 never really dieseled but would backfire if I didn't open the throttle as I turned the key off. Today after 2.5 hours of mowing WAY too tall grass I made a point to let it run for a minute WOT and then let it idle for a solid 2-3 minutes with the hood open. Turned the key and it shut right down, just like it should. Patience is always rewarded. Thanks again for your input.
