Stripped the carb down and cleaned it all out, only to then discover its slowly leaking fuel out the vent lines when parked. I did notice the float valve looked slightly worn but didn't bother to check for any stamped numbers on the float seat Does anyone know what its supposed to be? And I can then order and wait for the parts without stripping the carb again edit: It's a keihin FCR carb. Presumably the FCR MX 37 but unsure if these all have the same size float valve/seat, there's quite a few different keihin FCR seat part numbers/sizes
