Sounds like it needs a prime, or choke. Take the glow plug clip off. Put your finger over the end of the muffler, or the top of the carb and turn the engine through by hand a few times. You should see fuel getting sucked up the line and into the carb. After going through about 2 compression strokes, re-attach the glow plug and give it a try. You may want to open the needle up a turn or so also, just to get it running, then adjust it right
