Hi Ive put a cv carb back to stock because to many people have messed with it. My question is does the dynajet kit have a plug for the main jet air hole that needs to be removed. I dont have the exsp. to know if one has been installed. (Still having some tuning issues.) What I can tell you is that the hole on the left at the filter side of carb has a barrel in it with no bottom like as if there was a piece of tubing in it, the hole looks to be under 1/8th inch. The one on the right which I believe is the main jet air hole has a newer looking plug in it that has a bottom to it with a very tiny hole in the bottom, about the size of a sewing neddle. Is this stock or is there a plug that needs to be removed to finish the job back to stock. Thanks guys ORTIGO
