Hey all ? im not sure if this should be on the carb section so appologies if it is !
ive just bought a PHBH 28 fs dellorto carb .. the internals seem to differ from other PHBH carbs ive used in the past , especially the atomiser as its a 268 EB ? which differs to the normal AV type , has anyone used this type of carb on their lammy before ? would the 268 EB be the same as the AV268 ? it also appears to have a power jet sitting next to the choke jet ?... very confused ..
Thanks Guys ..

Isnt the F for four stroke rather than B for two stroke.
The S is left and a D for right for your screws.
A BS is what you need for a lammy isnt it?

Found this info on PHBH28FD where D = Destro = Right, as in adjuster screws are fitted on the right, as opposed to 28FS where S = Sinistra = Left.
