Jet selection advice prior to setup.

Just having my 1300 junior engine rebuilt, but with so warming...... flowed. 10:1, bigger valves, 10548 cam, etc..

Going to need some slightly bigger choke venturis, but as its running solexs, my dyno guy won't have much if any selection of jets when we dyno it.

Any advice on the jets or selection of, that I might need to buy in ready ?

It's running twin solex ADDHE40's

A rule of thumb for Webers is go up 5 on the main jet for 1 mm increase in venturi.
