Hey, I have a 1998 Yamaha 4 stroke F50AET 62Y - L - 407926. I desperately need a bottom carby. I have not been able to find one in Australia, Yamaha told me they had one in New Zealand then they decided they didn't. I can possibly get one from the U.S. but not till some time next year. If anyone has one or knows of one I would much appreciate it. Thanks, Steve.
