That will use the same threads as the homelite? its a 26 cc, ThanksMy recommendation is to replace head with Husqvarna T25 or T35 depending on size of engine.
This is not you issue but I had someone come to me once and tell me his trimmer would not advance line. I have to take it apart to get more line. Can you fix it for me? Took it apart and found the string wound backwards. I had a nice (in my head only) laugh about that.
