Thanks to everyone that contributed – and there were many of you. After the air cleaners were removed and I attempted to lift the pistons, neither one would budge! I removed the suction chambers and separated the piston/needle from the suction chamber. I used WD40 to wipe the sliding surfaces between the piston/needle and the suction chamber. It did not seem pitted but the surface definitely had rust impeding the movement. After a slight rub down and reassembly, it started right up, first turn of the key. Now, the “inquiring minds want to know” part, why would it start when one plug was removed?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Again, you guys are the best.
