Ive got a 360 in my cj5 just rebuilt less than 500 miles ago i put a holley 500 cfm electric choke carburetor on it with the stock manifold. I thought this would be a little rich and it didnt bother me i wanted to get it running then worry about jetting it down a little bit later. As it idles it pops like i have a valve set too tight but they have all been adjusted to a half turn tighter than clicking. so i drove it for awhile checked the plugs 1 was completly carboned shut dont think it could hardly spark 3 was a little better 5 was dark brown and 7 was a light brown to almost white. so i changed the plugs it helped a little bit but now number 1 is white 3 and 5 are almost black and wet and 7 is white. Sorry for the long post but its buggin me that i cant figure out what it is.
