Ok I won't take the control box apart. Just have to remove the control box to get the bottom of the cylinder off to clean up in there and find that pilot orifice.
Is the pilot orifice up in the cylinder bottom below where the pilot flame "flower" is? I have had the brass tubing off (in OP photo upper right) that goes from the control box up to just below the flame but could not find any orifice part.
With that tubing gone, and the gas on, depressing the red button makes a hiss from the hole on the control box where the tubing goes in by the red button, so I think gas is getting through ok. The tubing is clear, so that leaves up farther that needs a look.
I know to turn the gas off before removing the control box so I can lower the bottom of the cylinder.
