   Original Dellorto new old stock locking tab for UB & UA carbs. This lock tab keeps the top ring nut from unscrewing from vibration. If you have ever had this happen while riding you know what a pain it is. Overtightening your ring nut with pliers can damage your carb body and cause your slide to stick. Dellorto part number #5670NOTE: These locking tabs have been sealed up in a plastic bag since the 1960's and look great with very nice plating. |
