Today, we're going to change the Exhaust on a Honda GX120 Engine. First of all use a 12mm Hex Socket Spanner to remove the two bolts that hold the Exhaust in place. Once that's done you can remove the exhaust from the machine. It's good practice when replacing the exhaust to change the exhaust gasket as it compresses when fitted. Place the new gasket over the two studs, making sure it's seated correctly with the cut-out matching the shape of the port. Seat the exhaust over the studs and hand tighten the two nuts on. Return to tighten the two nuts with the 12mm Hex Socket Spanner. That's how you change the Exhaust Manifold on the Honda GX120. All the parts & tools needed for this task are listed in the description below.
