Linkert
MR-4 "Campy" Special
MR-4 Linkert carb with old speed needle trick by 1940's
HD racer Ben Campanale.
Power needle is removed from original position and placed through main nozzle.
This is how Ben Campanale won the 1938 and 1939 Daytona races and became a
motorcyle legend!
This specific example was made in late 2000 by Campy himself for Charlie Lecach.
