Remove the top cover from the mower, remove the carburetor from the engine by twisting it. Remove the top cover from the carburetor and dismantle the carburetor down to the throttle connection (click here for G4 carburetor dismantle video for extra help). Disconnect the throttle cable.
With the throttle connection removed from the carburetor you can now unplug the air tubing from the throttle control at the handle of the lawn mower and thread the throttle cable from the tubing. You should end up with the old tubing away from the mower.
Next grab the replacement tubing and thread the throttle cable through it. Attach the tubing firmly to the throttle control on the handle of the mower. Then reconnect the throttle cable to the carburetor (again there is a link in instructions above for help with this).
Twist the carburetor back onto the engine and replace the cover. The job is now complete.
