String Trimmers

Hi. I have a Weedeater..FeatherLite XT260...It decided it didn't want to run anymore..Can't get it started. I don't think it's getting fire. I took out the plug and put the plug wire back on and pulled it but couldn't see and spart..I'm not the best mechanic in the world but I follow instructions very well so if anyone has and idea to what my problem is your advice would very much be appreciated....Pete
