Echo PB-265 Trimmer

[pencap43]

I was wondering if anyone else was experiencing problems with this trimmer. My constantly bogs down when I first start it, even after I've been running it all day. I believe the carburetor needs to be adjusted. I say that because I replaced the plug, gas filter, air filter, air breather, and I've cleaned the carbon build up. I also run echo oil and premium gasoline and have no problems with my other 2-cycle equipment. I would appreciate any feedback you guys have because I really do not want to bring it to the dealer.

Thanks!
