Well my thinking was if i set the timing around 1.05mm then the cold start would not function anyway. So i might try to adapt the fast idle to the factory cold start knob. At least to get me some cold starting help! :lol:
This particular pump has the solonoid on the front to retard the timing at an idle for reducing the NOx fumes...(At least thats my understanding of it.) Now other people have just wired that to the shut-off solonoid to run at normal timing all the time. What if a put a mircoswitch that disconnected it from 12volts at an idle, to potentially reduce the "marbels in a coffee can factor :lol: " at an idle....If i were to do this, how much would it retard it?
also do i need to feed this solonoid 12volts when i set the timing on this engine?

You have to be careful with that solenoid. It could be a cold start mechanism that prevents the pressure regulator from opening. It'll increase the housing pressure, which will advance the timing. If that's what it is, and you have it activated and rev the motor up you could blow the seals in the pump.
Even if you set the timing to 1.05 statically and then pull your cold start out, it will further advance the timing.
So to avoid the blowing of the seals, i should just give it 12 volts all the time?
If it changes the timing do i need to do anything special when setting the static timing?
Static timing should be the same. Take some more pictures of the pump so we can see what it is exactly
