I bought two of these kits to rebuild the two Autolite 1100 carburetors I have on my '65 Mustang 200ci I6. It includes the control balls, clamps and washers I needed to rebuild my stock Autolite 1100. This was my first time rebuilding a carburetor and this kit + Ford repair manual for adjustment made things really easy. I took it apart, cleaned it, replaced what I needed and put it back together a few hours later. one on my car.
