Did your mixture screw seat come out or is it loose? Then this is the kit for you!

After years of adjustments of the mixture screw and material deterioration due to age, this has become an all-too-common problem. CB Performance has re-designed the seat to include a set of one-way barbs that keep it secure for many years to come.

The kit includes an installation tool and four new seats to upgrade a pair of IDF carburetors. Get those broken carbs off the shelf and back in your ride with this quick and easy fix.

This kit was designed to fit original Italian IDF carburetors. It is not recommended for IDF carburetors manufactured elsewhere.
