Greg,
The bar and chain you can get from your local mower shop (after market type). The carby diaphragms can also get from your local mower shop (max cost $20.00).
The fuel filter in the tank you can use an Oregon type (Cost about $8.00 max)
The clutch springs that will be a bit harder but I am sure that you could get after market springs again from your local mower shop. McCulloch part number 227360.
If you want I can supply the parts that you need but they will be after market.
