T5 Malossi Using Polini Venturi

evening people. I’m about to start on this engine and the set up will be Malossi 172, SIP Road XL standard 24mm carb with bigger Polini box and Venturi kit. I’d be interested to hear from anyone with a similar set up as I have no idea where to start with jetting. 

Thanks in advance, Steve
