dell'orto PHBN 12
i have take the carb out inorder to clean it and put it back in the bike, however i have lost the callibration specs for the idleing screw and the air screw as could you help me? asif the screws were out comletely, how far do i put them in until its factory settings
Norwich, NR5

From a Vespa forum:
General rule of thumb on the air screw is 1 1/2 turns out, this is the factory setting for all dellorto round slide and most flat slide carbs, normally if you turn the screw 1/2 a turn either way you should really adjust pilot jet. 1/2 turn in means rich pilot jet so go down 1 point on the jet same with 1/2 turn out on the screw go up on the pilot jet. then bring air screw back to 1 1/2 setting.

...thank you so much for the reply, I tried your suggestion and it runs like a beauty,
I have a Peugeot xps 50, with an am6 engine and dellorto carb, it now runs perfectly so hats off you your and your greater wisdom don't know what I'd have done.

Many many High regards
