Turn the LSN and HSN 1 turn out (richer). Start it up, if it doesnt start lean the LSN 1/8 of a turn. Do this until it starts. Also blip the throttle very fast when you are trying to get it to start, it helps alot. Did you heat the engine up? Once it starts, richen the LSN 1/8 of a turn and start leaning the HSN a bit until the idle is slow and consistent. Might want to also adjust your idle. I just like to mess with the needles a bit.
