Nilo, my mistake, you are correct.

Juice, Remove the blue collar from the low end needle. Then, close the throttle so that the opening in the barrel is only 1 millimeter (For reference, if you look at the white paper of a cigarette, they have grey lines that run around the outside diameter. Those lines are 1 mm apart from each other)

Now, with the throttle open 1mm, close the low end needle, and re-open it one and one fifth turns.

Then, reinstall the collar.

Next, start the engine, and get the high end adjusted with the high end needle. At that point, the engine SHOULD be performing properly. If not, it's time to contact the MFGer.
