When the filter element becomes damp or contaminated with too much engine oil, it will become moist and sticky, and the pores will be blocked, making it difficult for air to pass through normally, resulting in insufficient air intake for the engine. If the mixture ratio is unbalanced and combustion is insufficient, the machine will have difficulty starting and fail to ignite by repeatedly pulling the rope.
A damp and oily filter element will also affect the stability of the air intake. Even if it is barely started, it is prone to unstable idling, easy stalling, and weak power. If it is not cleaned or replaced in time, long-term use may also lead to an increase in carbon deposits, further aggravating engine startup and operation failures.
