Your Briggs & Stratton Classic engine uses a diaphragm to pump fuel. Yours has deformed and needs to be replaced. It is a very easy repair. Remove the air filter. There is a bolt on the end of the fuel tank nearest the spark plug. Remove this bolt. There is another bolt just behind the carburetor that holds the tank to the engine. Remove this bolt also. Now you should be able to gently pull the tank away from the engine. After the carb clears the intake tube, you can tilt the tank enough to remove the governor linkage from the carb butterfly shaft. Now the tank/carb assembly is loose and in your hand. Go to the workbench. There are 5 screws that hold the carb to the tank. Remove these 5 screws. When you lift the carb from the tank, you will see the diaphragm gaskets. Remove the old and install the new set. The 2 part diaphragm set consists of a rubber diaphragm and a paper gasket. The rubber part goes against the tank, then the paper gasket, then the carb. Leave the screws in the carb as you reinstall it, and the screw tips will align all parts during reassembly.
The diaphragm set is readily available at any Briggs parts dealer or online. Make sure you take the Model, Type, & Code numbers with you when you go for parts. These numbers are stamped into the metal fan shroud just above the spark plug.
Good luck!

    excellent solution, and guide. I never would have stumbled upon the method of removing the carb from the tank by myself. Also, the diaphragm/gasket, although available from B&S, was much cheaper on ebay.uk.

My Morrison weed eater keeps dying out I'm guessing it may be the carburetor dirty? I'm just guessing. What do you think the problem maybe?


If it starts and runs for a couple seconds and dies then yea, most likely it is the carburetor. If it runs for longer than that it will be something else

The Proper plugs


should be around .30-.35". You most likely have a dirty carb issue which will cause the bike to run poorly at lower RPMs as this is on a different fuel circuit in the carbs, know as the pilot jet. You may be able to run some carb cleaner through them. I recommend seafoam, or chevron techron. Mix according to the instructions on the bottle.
