is there a primer bulb on it? If there is pump it 3 or 4 times before u start it. Also put the lever on choke, and pull the cord until it wants to start. Then put the lever on half choke and pull the cord, should start. after about 15 secs put the lever on no choke and u should be good. The only other component is really the spark plug. If it still doesn't start, take the spark plug out by pulling the wire off of it and using a ratchet and socket to take it out. It should be dry, and maybe a little black soot on it. Make sure the electrode is not touching the metal probe. Hope this helps, good luck.
