1. The document provides instructions for performing an engine tune up, which includes checking various systems like the cooling, lubrication, fuel and electrical systems. 2. It describes how to perform a compression test to check engine compression and the proper compression levels. 3. The valve clearance should be checked and adjusted if needed since improper clearance can cause issues with valve timing.
