Run high side screw in to stop and back off one turn.
Do the same with low side but back out one and a half. Adjust with low side till it cranks.
Once its starts, hold saw wide open and turn high side Counter clockwise till the saw alternates between a high and low vibrato.
Turn the low side in at idle till the saw starts to idle up and stop. This should get you going.
