My Zephyrs run and the carbs adjust OK but my Lightfour tends to flood badly on the high speed circuit.
This diagram mentions seats for the needles but doesn’t show them. I suspect the Lightfours high speed seat has fallen out and now I can’t adjust the fuel flow on it. I sure wish I could find the exploded diagram in my files of the carbs which does show the seats. You might have the same issue.
