Question about Garden
My carb has a white valve protruding from it with no attachment. If I depress the red bulb, air flows from the valve. what is the valve for and where is the attachment?
It could possibly be the overflow return port for the carb. If so it should have a hose going from it to the fuel tank. You shouldn't have any open ports on your carb.

Change your air filter, spark plug, fuel filter, and oil. Then make sure the gas is fresh. Gas starts going bad after a month. Spray carb cleaner in hole underneith the fuel filter. Oh yea dont put more than 20oz of oil in it.

Well I have looked at my suppliers and they are showing it no longer available. So you may have to search around and find an old murray mower that no one is going to fix but has a good deck. good luck.

You have one of the infamous automatic choke Briggs carbs. These are supposed to close that butterfly that you describe, which is actually the choke until it is running, then it's supposed to keep it open. The problems is, if the diaphragm in the carburetor starts getting hard, or leaks, it'll kill the operation of the choke. They are known for their unreliablility to the point of where it's a shock to find one that actually works. You can fix it by replacing the diaphragm inside the carburetor, or by putting a spring on it that holds it open unless you manually choke it to start it.

Clean ALL the very small holes in the brass bolt that holds the carb bowl on.Some are VERY small and easily clogged. With bowl off and the bowl float hanging free, does gas readily flow? It should, and it should of course stop when the float is raised (putting the needle valve on its seat). If this event is occuring, then the main jet must be badly clogged. If no gas even gets into the bow. (not enough details).. then there is a vacuum lock or something strange going on in the fuel tank (cap). The threads of the fuel cap on a mower allow it to vent, preventing vacuum lock of the fuel flow.Start at the tank and go back in. Please repost as this is a good one.
