    i am running my polini kit with a 12mm carb, it dont run great, not as good as my mates racing 50 kit
    he has a Athena racing kit with a 21mm carb, but his has a flat spot, and i got told a 22mm is good, but then i got told, a 17.5mm is better.

    Need help asap, as im prob ordering a carb tonight

    Cheers
