Small Engines (Lawn Mowers, etc.): TB425cs gas trimmer, warranty dealer, gas trimmer

Question
I have this trimmer (TB425CS) that is about 6 months old. I have been using it for light duty yard trimming and for blowing the grass off my driveway. Everything was working fine until I was blowing some grass off the driveway with the blower attachment and it stopped blowing hard. It only works very slowly. I have taken the clutch out and it looks brand new still. Could I have burned the clutch up or is there another thing to look for. How can I tell if it is burned up?

Answer
Have you checked the blower assembly rotation by hand?  Is it difficult to turn?
Where did you purchase the trimmer?  Is there a warranty dealer in your local area?
If you install the trimmer attatchment, does the unit run normal?  If so, then the clutch is probably fine.
Let me know.
