I've just fitted a pair of new Webber ict's to my 1641 along with a csp linkage.Ive got it ticking over at fast idle ready to dial the carbs in but I'm not sure if I'm meant to disconnect the linkage and tune each carb seperatly .Any extra help would be great.Both idle screws are set equally and both mixture screws are currently wound out 2 1/2 turns but it does small rich at the mo .
