Your metering blocks are probably 3 hole .028, plug the bottom hole on each side on both metering blocks. Leave the 67 IAB in and change the MAB to .031. The overdrive is going to need the AFR a little fat on the upper end of the idle circuit and the 67 IAB will do the trick. Put a 35 nozzle up front and make sure the squirt is instant without bootoming out the accellerator pump. The adjustment is very close on a blue cam 30cc pump. You should not need a blue cam on the secondaries for the street. Orange cam for the secondaries should work. If you are going to restrict the T slot only the primary needs to be done. Make sure both T slots are even and not over exposed on both the pri and sec. Don't get concerned with chasing a 14.5 AFR number. You are reading an average of 4 cylinders. Plug reading and performance are more important than the number on the gauge.
