Hello, I just joined this forum in hopes that one of you might be able to help me out. I have my son's Husqvarna 128LD weed eater. I always seem to get it from him when it doesn't work. Normally I can figure the problem out, but I am now lost on what else to try. The weed eater will not fire at all. I replaced the fuel with fresh gas/oil mixture, cleaned the carburetor, replaced the fuel lines and tested the spark plug. I also checked the spark arrestor. It just will not fire. I know it is getting gas because when I pulled the plug out, the plug had gas on it. Any other ideas would be greatly appreciated. Thanks in advance.
