Can anyone advise me on how to tune the Briggs and Stratton carburettor on a zero turn Toro 16hp ride-on mower. Model No.286H7. Harold

We need to know exactly what kind of Briggs that is, Harold. Please post the Model, Type and Code numbers stamped or printed on the engine.

The engine was built on 6 May 2003. It is a single cylinder Intek of 470 cc capacity. If it has a Walbro carburetor it will be a model LMT (they were also built with Nikki carburetors).

The maintenance operations on the carburetor occupy a substantial amount of space in the single cylinder Intek manual, which you can download from the manuals section (subscription required). Here is the basic maintenance instruction:
