Remove the cylinder head

Lift the cylinder head away from the chassis to expose the piston.
Remove the cylinder head.
During reassembly, perform the following:
Make sure the two black piston rings are aligned in their grooves so the piston can compress properly in the cylinder head.
Apply two-stroke oil to the piston head and the cylinder walls before reinserting the piston.
