Genuine part in stock (as advertised) took 6 weeks to be available.
While the customer service was responsive and truthful, and a refund available I fault the webmaster for not disclosing that the part was not in stock, in fact back order status, with no fulfillment date.

Had to completely disassemble the engine of the trimmer. This was a husky 128dl trimmer. I had to replace this twice. The carb was running too lean/hot. I didnt know that the first time. So, the second piston and cylinder I installed, I also just replaced the carb and adjusted it correctly. After that, it ran great! Remember to lube all the engine parts with 2 cycle oil prior to assembly!
