Due to the effect of ethanol on cork we have devised a new method of sealing the throttle spindle seals on HD carburetters.
The kit consists of 2 ‘rubber’ seals and two spacers (enough for one carb). The rubber seal is placed on the spindle with the lip towards the carb body and the retainer is then pressed into the spindle housing until flush with the body.
The new seals give an efficient seal against air leaks which will not degrade in Ethanol added fuels.
Note; The bore of the retainer is larger than that of the spindle so as to give a clearance. The existing seal system kit are still available under part number WZX 994.
