    This depends on what kind of engine you have on the mower. If it is a Tecumseh, there is a metal ring around the base of the bulb that you can remove with a needle-nose plyer. Remove and replace the bulb and ring. The ring important, install it by using a ratchett socket one size larger than the bulb. Place the ring in position and using even pressure on the socket the ring will snap into place.

    If it is a Briggs engine there is a plastic ring at the base of the bulb. The application is the same but you should be able to snap the ring on with your fingers.

You should be able to remove the old one with a screw driver or needle nose pliers. The new one should have a new gasket with it.

My briggs and stratton 158cc 500series push mower primer button melted from sun. how do i replace it?

There is a tab on either side of the carburetor right where the primer bulb sits. You can depress both of these tabs with a screwdriver and pry out the plastic ring that holds the primer bulb in place. You can purchase a new primer bulb (with a new plastic tab) from a local mower shop or from a small engine repair shop. When you install the new primer bulb, put the rubber bulb in first then put the plastic ring on top and press it in until the tabs click on each side. It should work correctly after the tabs are clicked properly. You can take off the air filter and look into the carburetor to see if the unit is priming correctly. I hope this helps you out.

I have a yard machine mower model number 11A-549R729 that will not stay running. Have replace plug,drain fuel tank and clean carb. If you push the primer bulb it will continue to run. But once you stop...

Your carbs main jet is blocked. Using the primer supplements the fuel input and keeps the engine from becoming fuel starved.

You need to remove the main jet and run a strand of fine wire through the jet to clear it.
