Walbro no longer suggests default settings in their service manuals. They refer you to the service manual for the equipment that the carb is on for default settings. 1 1/2 turns out from bottom on both the high and low needles should get you running w/ further adjustment required from that point.
If you take the limiter caps off, count the number of turns it takes to lightly seat the needles. That is your "factory tune".
