# Remove the rocker cover from each cylinder head unscrewing two hex socket head cap screws from the rocker box on top of the cylinder head with the hex key supplied.
# Turn the propeller 2 revolutions counter-clockwise and see about the motion of both valves. The propeller turns approximately 260° from inlet valve stops action to exhaust valve begins action(i.e. both valves will be closed).Turn the propeller clockwise approximately 130° from exhaust valve begins action point. The piston should now be stopped at the top dead centre.
# The required valve clearance is between 0.04 mm and 0.10 mm (0.0015 to 0.004 inch) measured between the valve stem and rocker arm. Use the 0.04 and 0.10 mm feeler gauges to check clearances. Usually, the 0.04 mm feeler gauge will pass through the gap: 0.10 mm gauge should not.

  1. Remove the rocker cover from each cylinder head unscrewing two hex socket head cap screws from the rocker box on top of the cylinder head with the hex key supplied.
  2. Turn the propeller 2 revolutions counter-clockwise and see about the motion of both valves. The propeller turns approximately 260° from inlet valve stops action to exhaust valve begins action(i.e. both valves will be closed).Turn the propeller clockwise approximately 130° from exhaust valve begins action point. The piston should now be stopped at the top dead centre.
  3. The required valve clearance is between 0.04 mm and 0.10 mm (0.0015 to 0.004 inch) measured between the valve stem and rocker arm. Use the 0.04 and 0.10 mm feeler gauges to check clearances. Usually, the 0.04 mm feeler gauge will pass through the gap: 0.10 mm gauge should not.
