well i went to a #64 jet,#31 squirters,white pump cams,a #9 secondary plate and it seems to work good.there is no choke plate in either carb since i live in sunny so. california.i might try a 50cc reo pump though and see what it'll do because of the large plenum and long runners to the intake valves.also my dual carb linkage is set up right now for both to open at the same time instead of progressive.again this combo seems to be working quite well and feels really responsive when i hit the loud pedal.my friend did a really nice job in restoring the intake and zinc chromating the carbs
