I agree w you 100% but the Zeniths have a fairly wide spec and it's adjusted by using different sized washers under the needle jet. Think of the sealing washer when you screw it into the casting, they actually have MB part#s for .05/1.0/1.5/2.0 mm. I raised the float level w a thinner washer when I was having another issue which I had misdiagnosed at the time, (honestly, I was just chasing my tail but that's another story). I'm thinking that I made it too high because while I solved the original issue, now the car is not running optimally and I think I'm overfilling the carbs, even though the current washer is about 1mm.
The range is about 2mm according to spec sheet, (of float height). It's hard to measure w great precision because of the design and the upside down float is not level when resting but I can get close. Thanks for your input.
