My Briggs & Stratton 35 Classic is smoking alot and not idleing at the correct speed. It is also revving up and down quite quickly, and when i stop the engine the Exhaust Muffler is smoking. I have tried to clean the Spark Plug and clean the Air Filter but this has not made a difference. Can you please give me some advise as what i may need to replace?
Thank
Carl

Replace the carburettor diaphragm fitted between the carb and the tank. Remove the tank complete with carb, then undo the screws holdng them together.

Cost pennies.
