1 / 2Description
Keihin 1062-814-2100 is the complete float needle valve for PWK33, PWK35, PWK36, PWK38, PWK39, historical PWK41 and FCR-MX carburetors. It controls fuel entering the float bowl, closing the inlet as the float rises and reopening it as the fuel level falls.
The complete valve assembly is shown at callout 8 in the standard PWK33–41 parts diagram. FCR-MX support is tied to the exact 1062-814-2100 item and does not extend to the broader FCR family; applications using 1062-814-2101 are separate.
Match the full 1062-814-2100 number and callout-8 position when choosing this part. It is the float valve assembly itself; the related spring clip is a separate component with its own part number.
