24mm DellOrto PHBL with a Metrakit filter and a BUNCH of 6mm jets high 90s down to a 78. It's missing the choke lever (available from dellorto direct), and someone shaved the top of the carb back before I got it. I never needed to choke it. I ran this on my Gila, but am putting together a smaller top end on my ZA50 and this carb would be overkill for my set up. It's basically a giant PHBG with a race float and a 6mm main jet. Pilots are the 5mm. I'll send this out priority to the lower 48 with the jets and the air filter, for $75.00.
