Most of you know that Honda offered a mod kit for the 85 ES/SX carbs to fix the cold start issue. Recently I have rebuilt a few carbs that had a different start up jet in it. This different start up jet is what Honda sent in the mod kit. See the pics. The jet on the left is the mod kit jet and the one on the right is the original jet.
MFW, this is what the inside of your carb looked like.
