I don't understand your question....
or maybe you don't understand the function of the parts in question.
During a cold start, the idle speed is faster and the timing is advanced slightly.
These are two separate things. The idle speed is faster due to that lil solenoid that pushes up on the throttle. The cold timing advance is one of the two plugs on top of the IP (the other is for the fuel shutoff solenoid). It pushes the advance arm on the driverside of the pump. Btw, this is why your truck rattles more when you start it cold.
When cold, if you have the timing advanced too far and the advance mechanism on the IP pushes it further it can be bad. Feels kinda like when you start to run out of fuel, the engine gets random revs when it should not.
My solution was to unplug the advance on the IP as it is not needed.
I just wanted to say the word "advance" once more....

I understand what it does now. That's what I thought it did but I was confused why you talked about it. Lol. I thought you were inferring that it advanced timing throughout the whole rpm band. My bad. Haha
And as far as being bored .001 it was like that when I got it. I'm pretty sure that's what he said when I got it from him but back then I didn't know about cavitation.
