  2. Ensure the crankshaft is in a top dead centre by turning it clockwise. You will determine this by looking at the crankshaft from the flywheel. When you do this, the crankshaft will relax, and the valve will no longer be open.

  4. If the clearance is small, increase it by pulling out the valve and grinding the end of the valve stem. As you grind, ensure you do not remove too much valve stem, check by regularly measuring the length.
  5. After doing this, lubricate each valve stem. While lubricating, ensure no lubricant goes to the tappets or endpoints of the valve stem.
