Early Carburetor Kit

According to the parts manuals, variants of the "early" carb were in installed N600's up through chassis #1500000, but they are interchangable so your Honda may have had a different one installed at some point.  Check the shape of the float bowl and compare it to the parts breakout on this page.  The early float bowl is 5-sided and "squarish" in overall dimensions.  The "late" carb has a more rectangular float bowl.

We also carry the throttle vacuum piston.
