BF3 Post purge

Options
May I ask a question?  I've just come across a Riello BF3.  The problem, the oil does not shut off during the post purge cycle.  At first I thought it was the oil valve stem but no.  Then I thought it was the post purge timer but that's not it.  I tried a new pump thinking the valve was fouled. (the filtration is poor, FB4 from an old tank single pipe to the burner.)  I haven't ruled out the stem even though it's fresh out of the box.  The reason I say that is even if I remove the solenoid the oil is still delivered though it seems to have a restricted flow.  Am I missing something?  Any help would be great, Thanks.

Peace

Matthew
