Master repair kit for single HIF44 1.75" carb with integral float chamber. Kit includes new throttle shaft, bushings, butterfly (without bleed valve), .100" jet, float needle/seat and the gaskets/seals needed to complete a comprehensive rebuild. Reaming or machining the carb body is necessary to fit the bushings, but this will allow a worn body to perform like new. Genuine SU. Appearance and contents may vary from photo.
