I'm rebuilding an Oct 26 1986 FJ60 carb today. When I tore down this carb it was missing the G shaped retainer clip that earlier carbs have which lives under the accelerator pump plunger and spring. On early carbs this retains the pump check ball. I don't think anyone has been into this carb before, so I'm wondering if the later carbs used this clip or not. I have the clip from another parts carb I can use if I need to, but not sure if I need to...
