Charles,
You know for a fact that your firing order is correct, right? And that the
cam/crank timing is correct, as well as proper valve clearance?
When you pull each plug wire without noticeable drop in engine revs... you've
got a serious compression problem. Have you taken a compression check or done a
leak down test?
One other check; carbs are still ganged together (connection between the two
hasn't slipped)?
