Kai if you know how to take it apart on you go, just make sure to align it up properly though.
Well if you don’t know have no experience taking cars apart putting it together (properly) then don’t try it.
Do as Kai said clean the junk and spray carb cleaner inside it
Whats wrong with yours Kai?
Let us know how ya get on,i've got the same prob,redex seems to have improved it n i'm gonna get the garage to clean it when shje goes in...spray carb cleaner,is that a halfords job or a proper car spares place? worth a bash beforehand,don't much fancy taking anything apart!!!
