Cambridge lambretta show a new table about "Basic carburettor settings"

http://www.lambretta.co.uk/downloads/carbjetting.html

When you compare with the last list and many many set-up present here, it's richer between 1/4 ->3/4 (needle smaller/atomiser bigger) and poorer after 3/4 (mainjet).

I try it since 1 month (mugello 186), it's very good, more torque...
