Air Jet Tip

[atufte]

Hello

I'm about finished with my Vespa project, but need some few finishing
tips, i have a PK XL/POLINI 130, and a dellorto 19/19, Sito Plus exhaust
and so on, but what dimension "air jet screw?" do i need for my carb on this
setup, this carb used to be on a V50 engine with 75 Polini, Sito Plus, etc...

Thanks in advance...

If you mean the idle jet use a 45.

Every engine differs - there is no such thing as a standard 133 with 19/19 jet! bt to help you with where to start with:

check some 133 plus 19/19 setups here: sfs.alexander-hepp.de/
