After Howe 340 is adjusted, the valve oil is reduced.

Improper coordination and adjustment between parts.

According to the owner's guide, the main reason for the decrease of valve oil quantity after the adjustment of Hao 340 is due to improper coordination and adjustment between parts, such as excessive clearance between piston and cylinder, excessive clearance between intake valve rod and valve guide, and poor ventilation in crankcase. At this time, it is necessary to find professional maintenance personnel to adjust. When the engine is working, it is normal that the oil quantity decreases due to high temperature and heat dissipation, but if the oil consumption is abnormal, it is necessary to investigate the cause of the failure in time.
