How to Install new Cylinder Head

Remove

1) See below on how to remove the plastic covers.

2) Remove the muffler

3) Remove the carburetor and manifold. There is just 2 bolts under the air cleaner cover to remove the carburetor. Once the carburetor is removed, there is just 2 bolts to remove the plastic manifold.

4) There are 4 cylinder head bolts. Insert a hex key into one of the holes in the air fins in the top of the cylinder head, and undo bolt. You may need a vise grip or similar to get the torque to crack the bolt. Undo all 4 bolts

5) Pull off the cylinder head.

Replace

1) To reinstall, make sure the rings on the piston are lined up so that the ends of the rings will compress against the mark on the piston. Push on the cylinder head as you squeeze the rings with your fingers. No tools are required. Rotate the cylinder head so that the carburetor intake inlet is on the correct side (left side of engine looking from the pull unit side). Holding the cylinder in position, rotate the flywheel and make sure that the piston moves easily up and down inside the cylinder. You can put a few drops of 2-stroke oil into the carb inlet to lubricate the piston. If ok, Install cylinder head bolts and tighten snugly about 1/4 turn from firm. Reinstall the exhaust, carburetor parts, and covers in reverse of their removal.
