Re: Diesel Shutoff
This is something I have seen on a few boats and a ton of heavy machinery. It should probably have at one time had a spring on the throttle adjustment down on the fuel pump end of things that would help you feel it. It may still be there, but it probably is not all that springy anymore.
Basically all this is doing is starving the engine for fuel by completely shutting off the throttle to a setting where no fuel at all should be going to the engine. The little spring that may possibly have been there at one time a long time ago would just have been to kind of keep the throttle from going there on its own. Since the cables are usually stiff enough, I never worried about it.
It is good to learn from your mistakes, but much better to learn from the mistakes of others...
