Does anyone know a good starting point for adjusting a 1956 Mercury Mark 25, AJ 50 A carb. Idle and high speed? I'm starting a motor I have never seen run before. I have changed the coils, points, wires and plugs. Also replaced the carburetor float and cleaned it up.

1.5 turns out on each will get you started. The final adjustments need to be done after the motor is warm.
