Ok, i'll try to make this clear as possible...
I understand with phbg carbs what the letters stand for-
AS -Clamp mount, left mixture adjustment
AD -Clamp mount, right mixture
BS -Spigot mount, left mixture
BD -Spigot mount, right mixture
Here's where things get whacky. Right or left hand mixture i assume pertains to the perspective of looking into the mouth of the carb, not from the mount side. That said, the carb pictured below is an AD phbg, seeing the mixture adjustment is on the right, correct?
I have a motobecane with a shorty intake, so i need a clamp mount 19mm PHBG that i can access the mixture adjustment from the magneto side of the bike, but i cant find a 19mm AD, only 19mm AS.
WTF?
