Carby question

Hi I have a 2010 SR50 Biaggi rep with a Malossi MHR replica 68cc cylinder, Giannali exhaust, polini super speed variator, Malossi delta clutch.

I have just purchased a Malossi PHGB 21mm carburettor, is there anybody that can give me a base setting.

The carby cam with a W16 needle, and a 50 main jet.
