A couple of things.......
When taking a compression reading, you can feel and see the actual
compression strokes. So how many compression strokes are you registering? What reading
did you get on the FIRST compression stroke for each cyl?
Check that your points are in good shape. The contacts tend to corrode and
develop a high resistance.
Before you change carbs, drop a couple of teaspoons of gas down each carb and
see if it fires on that amount of gas.
