One more question about this....when it is cranking, the plate how much should drop? I have a circular space of 1-1.5mm, while is cranking.I ask because I think that maybe have some air leak which I could not test enough with ISO octane spray.I can show you in the link below how is starting with engine warm .

When cranking the sensor plate should deflect ~2-3mm, so yes, you may have some air leakage.
What is the condition of the spark plugs, rich (sooty), or lean (dry)?
From your descriptions of starting, we might expect lean.
Have you inspected the fuel strainer that is in the inlet fitting of the fuel distributor?
Is the fuel in the tank fresh, or has it been sitting while all the engine work was done?
