When the Coupe was first delivered it suffered from some issues that made my brain sag.
Terrible filling speed and blow back.
Swingometer grade accuracy of the gauge.
Both did end up getting fixed on one of it's trips back to the factory.
The filling speed was related to the "o'clock" location of the breather holes you could see in the facing. They needed to be at the top and the pipes connected to them needed an untwisted run. Once this was done the filling speed and consistency improved greatly.
