havent got a clue
But i know carbs have to be set-up alot more often than injection. SO maybe worth getting it set up on a rolling road by someone that knows about carbs. There used to be a good carb rolling road in Sittingbourne (Kent) called BD engineering, they set my mates 1.4 Nova SR up on twin 40's and it went like rocket, i was very impressed, but wouldnt use them for injection cars
