My lawnmower engine has recently being producing smoke. The plug carbons up very quickly and the engine stops. Clean the plug and away I go again - for a short while. Its now got to the point were the engine runs for a minurte or too and then conks. Tried changing the plug, cleaning air filter etc My grass is growing as I type!

It sounds like the rings might be worn and may need replacing. Do you use the recommended Briggs & Stratton oil in the engine? Using the wrong oil can be hazardous to the life of the engine and will shorten the life of your Briggs & Stratton engine.
