I know this subject has probably been covered a hundred times. So sorry if go over the subject again I am going to refurbish my carbs getting a kit from Paddocks tomorrow. How hard is it to do? I've heard people going on about inexperienced people not getting the needle centered but as far as I can tell the needle fits into a hole and is held by a grub screw. I stripped down the left hand card ready for an ultrasonic bath unfortunately the choke setup is different from the right hand carb. I’m in for a world of pain I think. Paul
