At that point, you've got to replace the primer bulb to get your chain saw up and running again.
Things You Will Need
-
Pull the black, rubber spark plug boot off the spark plug on the rear of the chain saw engine to prevent the tool from starting accidentally.
-
Examine the primer bulb on the left side of the engine, above the pull rope. Place shop towels underneath the primer bulb to soak up fuel in case a drop or two runs from the fuel line.
-
Insert a T8 Torx screwdriver into the four screws on the recoil housing surrounding the pull rope. Turn the screws counterclockwise to loosen and remove the screws. Place a flathead screwdriver underneath the recoil housing and pry it off the chain saw.
-
Grasp the primer bulb at the top right of the housing and pull it outward gently. Pull the fuel line from the rear; use needle-nose pliers if necessary.
-
Insert the fuel line onto the rear of a new primer bulb. Align primer bulb the mounting tabs with the mounting ring's slots on the chain saw. Slide the new primer bulb inward and press it inward firmly.
-
Replace the starter housing, insert the screws and tighten them clockwise. Press the spark plug boot firmly onto the spark plug.
