Finally finished the instal using a horizontal termination.

converted from Propane back to NG...Pilot light lit...

But can not get the main burner to fully light. Just a little splash of flame from the front tube.

Now what?
 
Had no way to check pressures this evening. Did however try to adjust pressures , counting turns made to bring it back to settings, with no changes.
 
When checking voltage at block I have 679 ML when thermopile is disconnected, 260 MV when connected. Is it eating the voltage trying to activate the valve?
 
Yes
the one removed looks the same my code number is 0907202

If you can hear the gas valve "CLICK" when you turn the unit on, the valve is trying to supply gas to the burner.
Pull the burner, remove the burner orifice with a 1/2" (or13mm) box wrench or socket & see if the tube behind the
orifice is blocked by a spider's nest... It'll look like a white diaphragm across the ID of the gas line.
This happens a LOT. A Q-Tip or a pipe cleaner will clear the nest. Reassemble & give it another try.

Did all the above, no blockage found.
Do NOT hear the click when trying to fire up... Do get a click after pilot light has been shut down.
