Pilot Flame is not what it should be
Have a gas pilot question on a heat and glow fireplace. It's a 8000TDR Nat gas log set. The system has a powerpile and a thermocouple. The pilot flame impinges on the power pile but falls short of the thermocouple. The set looses the pilot flame irregularly. The pilot flame is weaker than it should be. I can't adjust it any higher. Gas pressure is 5.38"in. Going back to look at the pilot assembly. The pilot gas tube is 1/8" od, so I am looking for an obstruction.
Is there an orifice or restrictor plate on the pilot assembly or gas valve connections of the tube?
This is a robertshaw 710 LC gas valve. The pilot set-up, except for the bracket is also common.
The inside of the fireplace is cold cold cold, so makes me wonder if there is condensate in the tube.
Robertshaw pilots do have a NG or propane orifice at the pilot connection.

Blew out pilot feed tube and pilot assy. Good as new.
