Ok, looking at the pictures…someone should be slapped for blocking the emulsion holes like that. They should be tapped and blank jets or screws screwed in there. That’s crazy.
You need one emulsion hole of .028 at or slightly above the float level and one of .028 at maximum float drop.
I‘d probably use 2 and 5 and block 4 because 1 and 3 are already blocked.
