2nd I took the air filter housing off and the two screws out of the carburetor.
3rd I removed the gasket and the o-ring from the carburetor. Then took the clip off the holder for the throttle cable.
Last, I put everything back in reverse with the new parts and gasket and o-ring.
Afterwards I replaced the spark plug.
