This kit fits the "early" style carburetor with a diaphragm on the side. Includes all of the gaskets and o-rings, properly sized float needle and seat, slow jet plug, and accelerator pump. Fits the early production Honda N600 sedan.
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. Click here for the late carb kit.
