i found an nos themroquad and decided to give one a try. it is a late 70s carb. id have to get the number off it. the engine is a low compression 400. honed, new rings small cam, performer intake and headers. it had an awful hesitation and sometimes pop when you would crack the throttle so i drilled the squirter out to .031. it looked like it was about .024. it didnt seem to change much. the acc pump has the 2 holes i moved it to the end that didnt really seem to change much either. i took it for a ride and if you hit it while under a good load it would pop and just run awful. there was also a bad stumble when shifting into each gear. i adjusted the rod hieght and that seemed to make it better but when you rev it up it still isnt as clean as it should be.
