Man,it`s not about who is wrong I jast must try to belive.
I am not going (as I know that isn`t much) to NOT starving the inlet,as fact I`ll use almost stock CSd or KSB,it is same task as you do by lever(pull) or by electrik by cut off el.valve.
As I see only diferent is I`ll use new plate (WITHOUT el valve) and put ball valve,and connect small tube and rest.
Of corse with el. cut off valve its just ON and OFF mode,ball valve made adjustable.

im not saying you are wrong.. i just dont see how you are going to accomplish this is all..
when you pull the cold start lever, it advances the timing 6*.. only at low engine speeds tho..
internal pressure will eventually take over, and advance it past what the cold start lever will do..
sorry, but the cold start doesnt do anything in the effect of a valve..
and that valve RETARDS the timing.. it does nothing for advance.
Valve on = Retarded timing.
valve off = Normal timing.
that valve RETARDS the timing, not advances it..

But what if he sets it up so that valve off equals over pressured thus over timed engine. Say pound it down until the pressure is at 80 psi at idle for instance. That would replace valve off = normal to be =advanced timing. Now throw in the ball valve and slowly close it off. Now we have less advance or maybe even normal advance and the ability to go less advance.
Am I thinking this correctly? I see the pressure differences in the different fuels I run and I think I know why he wants this ability. The only thing I question is flow. Not enough fuel will reduce speed and power. Not good at the speeds I run but might do OK at city speeds.

you NEVER EVER want to starve the pump inlet.. ive heard that it causes cavitation in the vane pump.. leading to erosion..

Hey you're talking to a Soil Scientist bub. You mean WEAR not EROSION. Erosion is a soil and water thing. Mechanical part to part with lack of lube is different.
Just so we have our terminology straight.

explain the blocks of 7.3 IDI engines rotting away from cavitation?
there is no mechanical metal on metal wear..
if you drip water on a rock, eventually, the water wears thru the rock.. same thing with metal..
the diesel is water, the steel is soil.. lol.

Cavitation and soil erosion are two veeeery different things, just saying. Cavitation deals with a solid traveling through a liquid at such high speeds that it creates a vacuum in its wake strong enough to cause a vapor bubble--like a vapor trail off an airplane wingtip, only in water instead of air. Not the same thing as water dripping onto soil or rocks over a period of days/years/millenia. Both can be very destructive, but for very different reasons.

And that concludes my thread. Thanks folks. I am now moving on from the motor to the floor pan.. Winter is near.

you can cut steel with water..
i rest my case...

I have seen that! Pretty Awesome and Impressive. Makes you think twice about that glass of water now doesn't it? How many PSI? We think our IP develop pressure. Not even close.
Only thing cooler is the robot lasers.

New diesels are getting up there 20,000 psi or so...I read it somewhere.

more like 30,000psi...

Technically I would have to agree that rust is a form of erosion that water inflicts on steel as well. So I take back my slam. I just have a dirty mind most times.
