After years of wear and tear, the seats of the mixture screws on the Weber IDF carburetors have the tendency to come loose.
Very annoying as it renders these valuable carburettors virtually useless.
This special set consists of 4 newly designed seats with one-way barbs and the appropriate tool to insert them.
Get those broken carbs off the shelf and back in your ride with this quick and easy fix!
Please note that these seats are of the "one step design with barbed collar".
For the "three step design with chamfered nose", please see HERE.
