Product Description ?

This is a genuine OEM approved replacement part designed for use with Toro lawnmowers with Tecumseh engines. By pressing on the purge bulb, it will force fuel into the fuel line from the fuel tank into the carburetor. Once the carburetor is full of fuel, the excess fuel will be purged back into the tank in the fuel return line. At some time the primer will lose its elasticity or crack and need to be replaced. It is made out of rubber and it is sold individually.

    The parts were correct and worked fine just a little upset with delivery, paid extra to get it here in two days and didnt show up up for seven days. I get the covid thing, so just say no matter how much you spend it will not get here for 7 to 10 business days. Just saying!

    Tools Used

    Screwdriver, Pliers, Socket set, Wrench Set, Nutdriver

    Pulled the carburetor off and rebuilt it. The idle jet was completely clogged. You'll need a very small diameter wire to clean it. I used a strand of copper wire. Reassembled and runs like new. Check for videos on how to do it. Very simple if you have ever turned a wrench.

    Use socket to replace spark plug. Air filter does not require any tools. The primer bulb is held in place by a retainer ring so you need a sharp tool to get behind the ring and pry it out. Very simple to do.
