....Hi Everyone, Ok I want to order I size smaller carb jets {from 71/83 to 70/82}. I went to the Jeg's web site & got confused. They have what they call a 'Standard Main Jet" #81 with a hole size of .093". You get two of these for $7.... Now they also have a kit for $15 that has 22 jets in it, sizes ranging from size 80 to 90 {two each}. So my questions are; 1) Are these the same jets? 2) Are there more than just primary & secondary jets in a carb? {I'm also ordering a Holley carb book!}.... THANKS Bill
