I wasn't their so I can't really blame them for it breaking but, I am more upset that I won't be able to take the to the relatives house for thanksgiving but oh well life goes on. Thanks for the help I just wanted to know if its a common problem or not, or if the mechanic messed up. Sil I don't know if they broke it or its not working right all they told me at this point is that they ordered a new one and its on the way.
Was it running when you took it there?? I'm not entirely sure, but I don't think it would have been running if the tensioner was broke. Maybe if just a small piece of the plastic that the chain rides on was broken off, maybe.
