You placed your air tube in the same place as shown on the top of Page 15? By my reading, that might not work on a WT. Look at this diagram from Page 2 of the WT manual:

It seems to me if you blow in the hole surrounded by the green circle, you won't achieve much because it is blocked off below the main jet. If you blow in the hole surrounded by the yellow circle, and you have the high speed mixture screw backed out several turns, it should pass air. If it doesn't, it may be time to take physical action regarding a possible blockage.

Note that if the diagram is correct, you also can't drive the main jet out from the green circle hole, because the plug is pressed in against a shoulder, and the bore the main jet is pressed into is smaller.
