So your getting lots of fuel to the cylinders okay? Start checking primary ignition voltages on the coil. From what you described earlier it sounds like it may still be a vaccuum leak either intake manifold side or a line. How do you know its a weak spark?

Ensure that its not flooded nowand cylinder wash didnt lower compression in the cylinders causing it not to start. I would take out the plugs, clean them up, have a very good close look at all vaccuum hoses and intake hoses coming from the carbs, ensure they are tight. Charge the battery good and try it again. It sounds like you have fuel and spark, so it obviously something you did while taking off the tank that your missing is my guess.
