Under each carb is a bit that sticks down with a nut on it, wind it one flat at a time clockwise (I think, its bin a while!) till you get it how you want it. Thing wit twin carbs is they tend ot go out of balance, best cure is to go to your local rolling road and get them to set it up for you.

To be honest if you have to ask how to adjust the mixture on twins, you should leve it to someone who knows how.
You need to have experience of adjusting a single SU before to progress to a pair.

Very nearly got it, goes like a good un now , still slightly out of balance but I can sort it when I have time.

Does anyone know the dwell angle by any chance for a 1275?

Thanks,
