Where should the low and high end be set for first run..?

Low and High should be at 2 turns open for ANY engine ever made..You start it up, it WILL be too rich on both..You will LEARN to set your carb BEFORE you fly the plane..You WILL NOT damage the engine doing this..Its ELEMENTARY....
Set the high a little rich, then set the low for good transition, then re check the high and go fly....NOTHING TO IT, live a little ....

Do what Ralph just said.

Manaul states 1 3/8 low end & 1 1/2 on high end.

Thanks i will start there and tune it in before flight.
