Adjust the grinding machine to an angle of 44.5 degrees for the exhaust valve and 22.5 degree for the inlet valve. If the edge C ( from Diagram of Valve provided on the post) of the Valve disc is less than 1.4mm (0.055 in) on the inlet valve and 1.0 mm (0.039 in) on the exhaust valve, or if the Valve stem is bent, scrap the Valve.

Answer (1 of 2): The repeated opening and closing of valves causes an impact on the valve seat. The valve and seat should provide a gas tight joint for compression of the charge in the combustion chamber. The impact leads to wear of the valve and seat causing poor sealing. To restore the sealing ...
