Product Details

This component functions as the primary mechanical screen within the positive-displacement pump circuit of STIHL two-stroke power units. The filtration media captures particulates capable of scoring needle valves or rupturing rubber diaphragms, thereby preserving calibrated jet clearances and ignition timing consistency. Service intervals align with the manufacturer maintenance schedule, typically every 25 operational hours, or immediately upon observing hard starting, idle surging, or visible feed-line discoloration. The materials resist chemical breakdown from standard unleaded and ethanol-blended fuels used in municipal and landscape maintenance applications.
