Important Notes:
This kit is for round shaft pump carbs only. If you have a flat shaft, use KR600F instead.
If your round shaft pump has a leather cup, you will also need to order a complete replacement pump.
Polish the pump bore and apply two drops of oil to the cup before installation. Do not soak the pump.
To clear ethanol residue, run a thin wire through all internal passages before assembly.
Carburettor numbers 7013596, 7025638, 7025662, and 7028149 require an alternate float bowl gasket.
