I have a factory air cleaner from Mopar preformance with the K&N air filter. The O2 is an autometer analog which ranges from 8 to 16 I think. Not the colors only style. I think is a quality part from what ive read. I can try the no air cleaner lid idea. Correct modified carbs will be here in a couple of hours. Since it was running sooooo rich could I be reading the crap in the exhaust waiting to clean/burn off on the O2. its right after the collector. I brought the MSD ready to run dist and coil today. I didnt install it yet. The set up does not use a box. Its all inside the dist. Ive been told the tach (5" autometer) wont work with the MSD the way my new tach currently works with cheapo 440 source Dist. Is that correct?
