    OK, after replacing the defective fuel pump and installing new OMC/BRP coils, I’m declaring victory.   Seems to run good now.   You’ll notice in the video that after tweaking the carb adjustments, the low speed needle knob needs to be moved to point downward toward the scale and at the very end of the video, the high speed needle was a little loose and opening richer and just needed the packing nut tightened up a bit.   Final carb adjustments will be done once it gets on a boat.
