Riello burner

1) photocells have slightly different numbers . See photo. They are the same length. Error occurs with both.
2) head distance I have now set to 5 mm
3) oil pump pressure set to 100 psi.
4) waiting on new nozzle
I measured the voltage into black control box which was 239V but I couldn’t get a voltage going to the solenoid coil. I tried with both photocells exposed to the light.

Black box was very dirty inside , this could be an issue since carbon is a great conductor.

Success . Installed new control box. Boiler sprung into life. Fan turns off when boiler not running I’ve adjusted air shutter. Manifold cover gasket leaking slightly. Thank-you everyone for advice.
 
Boiler breakers are a great source of spares… very friendly
