If your spark plugs are oiling up, it is because the the valve stem seals need replacing or your engine is worn.   As long as the engine does not smoke continuously, the news is not too bad.  I would suggest you change your plugs to a heat range higher to the one you are using now.  This will hopefully burn your oil, but you could suffer cold start problems as a result.

The carburetor adjustment is at the base of the carb.  There is a plastic shield which you remove,  that exposes to the the adjuster nut.

The idle adjustment is by the nut type screw on the inlet manifold, it has a tube attached on the top of it.

Cheers,
