@daddybloke They were used on very old cars and vehicles( pre-40s mostly) and little bit later still on some farm equipment.
By the 50s they were pretty much archaic and obsolete in all applications. Rarely used by then and after except in very niche applications.
They really only made sense with unpressurized fuel systems and F head (intake over exhaust) engine designs. Once those two concepts faded the updraft carb really had no advantage

@HumanEarth I can't think of one major manufacturer that was using updrafts on even lawnmowers after maybe the 70s, early 80s tops. They all switched to side drafts. Not saying there were none, but they were rare.
They certainly aren't used after the switch from flathead to OHV
