The WB's were sent out with the shortened reed block. You might have mufflers for the 110. If I remember right I was able to get to the needles ok when I tried using the stock mufflers. I think mine have tapered front ends and the needle holes. Maybe the taper let me get to the needles.
Over in the other 115 thread Keith details how to modify the carb.
There will be some more fixes coming soon so if you can't reach Keith or do not want to mod your carb feel safe to fly the engine just avoid prolonged WOT unless you have a ritch high needle. but the ritch high needle might cause it to have the KE burbles.
