they have RD on them
Ordered some from Allens now
Noticed today i had 2 different height needle jets in
i have 2 sets of PWk's and must have mixed them up as they are nearly the same.
One pair is 10mm and the other are 11mm overall height
Inside diameter seems the same but the question is how do the 2 sizes perform ?
Obviously the one set sticks out further into the mouth of the carb so what's the crack carby experts
