Good To Know
Q: Does this kit cover both the top and bottom carb sections? A: It includes the bowl gasket, fuel inlet seal, needle and seat, and all necessary metering components, so both the float bowl and throttle body areas are serviced in one kit.
Q: How soon should I replace the kit after a new ethanol fuel switch? A: Ethanol can dry out older gaskets within one season, so installing this kit at the first sign of a hanging idle or fuel drip from the bowl ensures consistent performance throughout the mowing season.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
