exploded view of mcculloch 335 carb?

my mcculloch 335 (2005)chainsaw starts but immediately cuts out. the tank has been washed out, spark checked etc.Been suggested I take it to a carb specialist to sort, seems a bit drastic though because knowing how repairers seem to `find other things wrong` and the subsequent costs involved, it may be better to bin it and buy new.
That`s why I`m looking for an exploded view of the carb, to have a go myself, nothing to lose.
Comments please
