Honda HR214SX self propelled mower
Honda GXV120 engine
Fuel leaking out of carb. Removed & cleaned with ultrasonic cleaner. Back on and still leaks. Removed needle, held my finger over hole, blew in fuel inlet and could here air. Soapy water confirmed it is leaking around the plastic seat. When looking at parts list, I don't see that the seat is included with either the float set pn16013-ZEO-005 or the inlet needle pn 16013-ZEO-005. Any knowledgable Honda people that can help?
