I just put my third blade adapter on, and it sheared off all of the star pieces in the first three minutes of mowing, just like the others did. I'm about done with this mower. Am I doing something wrong?
Thank you so much for this info!! I just put a cheap carb on my trimmer and while it ran ok, it didn't have enough power at full throttle. I found the high throttle screw you mentioned, tightened it down a bit and now it runs like new!!
