I have a 85 with the 258 carter bbd carb. Here is my prob. I can't seem to get my timing right. When I run through the gears in the higher rpm and at highway speeds the dang thing sounds like a diesal. I'm not sure if it's a timeing issue or valve issue but I have no probs at the lower and mid rpm and when I adjust timing higher or lower it is worse through the whole range. The card was new prob about 2 years ago before I bought the jeep. I've done the ford TFI convesion and I am running a gap of .045 I've also done the alluminum valve cover. Do you guys think switchin to the weber would solve my probs or can I five it another way any imput would be great
