Last try, its the fuel metering device that fuel has to bypass in order to have a runaway. In a 2 stroke detroit, the metering in the unit injector has to be bypassed, on a 6b bosch P-series its the port helix.
Fuel has to bypass the fuel metering devices in order to have a runaway. Not the fact that the operator has no input to the metering device. If fuel is flowing through the port helix or through the metering device in a unit injector. Fuel is still being metered to the engine.
Governor springs and flyweights balance operator demand to engine load, and set min max rpm. Those taken out of the equation, still has fuel entering the engine through the metering device, although the metering device may be stuck at whatever position.
Does any of that jive?

You are as heard headed as you stated earlier...
Read back through what I have said , and take a few minutes to think about it, it will make sense , you have said yourself that in the situation we described that it was out of the control of the goveroner assembly, thus making it a runaway. A runaway engine is running on a source of fuel that is not being controlled by the goveroner. Think about that really really slow and maybe it will make sense to you.

I think what Demons trying to say is that a runaway is a condition that makes the engine operate at a higher speed than its supposed to, thus causing it to blow apart. An uncontrolled fuel source would not technically be considered a runaway by this definition, if it does not make the engine go faster than its supposed to. I think.

........ the governor mechanism controls the fuel metering device..........fuel has to bypass the metering device to have a runaway, not the governor.
people tend to use the term Governor too loosely. I'm guiltly of it.
this thread isn't a runaway, its a trainwreck.........like you know someone died but you just can't stop looking.

You have stated all along that it was out of control of the goveroner that dictated a runaway, and I proved you wrong , although you won't admit it, and now you state that it has to be a fuel source out of control of the metering device, you changed your story.

OK...OK time for this one to end.
I don't want to have to close down this thread because the poor fellow who started it is STILL waiting on someone to answer his question.
It was a runaway!... It was an Uncontrolled fueling situation!..Who cares what you want to call it, lets either help the guy or stay out of it.
