When I opened the package ,I noticed black dirty grease spots on it. After looking it over it appeared to be a used part. It was not clean except for the pull rope and pulley inside which appeared new. I debated returning the part, but Decided to install it and see if it would work, and it did.
So I kept it because I needed to use my trimmer.
I think tho housing was used but the in parts were new and it works.But I wonder about the next time.
