I did download the manual. I couldn't find anything on the Low Needle (mixture) screw.

I'll have to re-download it. seems like I got a partial one. ends at page 17.

Is this a new engine? If so, then leave the low speed needle alone until you really feel it needs to be adjusted. Then the adjustment is done with the engine shut down and in very small increments. Turning it clockwise will close the valve (lean the low speed mixture), and counterclockwise will open it up (richen the low speed mixture). What I mean by small increments is like 1/8 of a turn.

Find "Mixture Control Valve" in the PDF. It's on page 23 of the actual manual. In the 17 page PDF it's on 12 of 17.
