Product Overview
Small horizontal engines often arrive with the same displacement label but different intake spacing, cable ends, and choke layouts. This PZ20 is useful after the original carburetor has been identified by dimensions—not merely by “125cc.”
Restores basic fuel metering for compatible Chinese four-stroke engines affected by varnish, blocked passages, worn float components, or damaged castings. Model names, reference numbers, dimensions, and configuration checks are kept together so the replacement decision can be made from evidence rather than a generic category match.
Measure the engine-side and air-filter-side bores, mounting pattern, fuel inlet, throttle cable end, choke type, and manifold angle against the original PZ20.
