[Fot] Weber carb question

[Bill Babcock]

One last thing, the modern variation numbers for Weber DCOE carbs start with
15, so if you buy a new 40 mm carb from Weber it's a 40DCOE152 or 153 which
looks to be identical in almost every way except float design to a DCOE9. In
other words, no one at Weber is doing development work on carbs--surprise,
surprise.
