25 Yamaha 1987 Needle/seat available?

[Fins]

The needle/seat inlet valve on my 1987 Yamaha 25 hp, motor stuck shut and prevented the motor starting. I removed it and cleaned it, s it was free and all is well. For now!
Does anyone know a source for just the needle and seat assembly, without buying the whole kit?
