Got the capacitor installed and now the Big Boy runs smooth thru all speed steps - go figure. Many thanks to Gunrunnerjohn, CJack, Zachariah, Alex, StPaul, Sinclair for the info to do the job. I soldered two 2 inch lengths of 20g wire to nubs 1 (red) and 3 (black) on the board and then the capacitor to those wires. I located the finished assembly rearward over the motor. I had to re route the collection or wires going forward over the motor to the left side of the motor.
Since I have never soldered before, I shielded the nubs on the board with heat shrink tubing and put a strip of tape just below the nubs to catch any debris and protect the board. I did a bit of practicing on 20g wire with .8mm rosin core solder and a Hakko FX888D and a watched a few Youtube videos. I found after a bit of experimentation the best temp was 585F, tinning the wire AND the solder nubs on the board AND using a long needle soldering tip with tinning worked the best. Regarding soldering, I have the mind of an artist and the hands of a butcher; the result wasn't pretty but it worked. If I ever take the shell off again, I might redo some of it.
