I'm currently running a 4.30 SG in my car. I changed to 2.76 peg leg once to do some cruising. When I did I had a problem with the car running way too rich and fouling plugs. I was running a 650 CFM Carter AFB race type carb w/o a choke. I got a strip kit and changed jets and metering rods w/ no improvement. So I just changed everything back to the original setup gears and all. I'm wanting to change gears again. This time either to 3.23 or 3.55 SG. I am now running a 780CFM Holley Street Avenger. Any guesses as to whether I'll run into the same problem? Paul L.
