The Mystery nobody can figure out

Intermittent Pilot Ignition

I still have this problem and it seems nobody can figure it out..

Ultimately I will be changing to a new powerflame burner due to this MYSTERY!!!

Loss of pressure across pilot solenoid

I have a Weil McClain model 580 with a Midco burner.

I am having a problem with the pilot.... it lights only intermittently when the boiler calls for heat or hot water.

Everything is freshly tuned...ignition, flame rod, all electronics ignition check out and there is excellent spark

The main gas pressure is over 6in col water. The pressure before the solenoid is also 6 after a 30 inch run past the regulator. The burner calls for 3.5 in column after the solenoid. BUT....No matter what I do the pressure drops to 1.8 max.

New solenoid, proper electric feed, everything clean but can't get higher pressure so the pilot is lighting only intermittently.

This is the mystery nobody can figure out...Any ideas are
