OK...this is going back to the Puch Magnum MKII 70cc upgrade that I posted about. I found an intake for it. It's a 14mm "tall" Puch intake. It has a round flange instead of a square one, but it does work. The carb in these kits are the Amal "tunable" kind. There are two adjustments on the side. The top one is the idle "screw." Is the bottom a main mixture screw? If so, how is it adjusted?

I'm a bit disappointed the the overall performance so far. There is improvement, but not as much as I expected, although I am not gunning it too hard. It will nail the ol' speedo, however, the acceleration isn't much better until you hit the midband rpms.
