Observe the following prior to/during reassembly of the engine:
• Clean each part carefully, taking special care with the piston, cylinder,
crankshaft, connecting rod, and bearings.
• Scrape off any carbon deposits on the cylinder head and the piston
head. Be particularly careful when removing carbon from the piston
ring grooves.
