60lbs? Not sure what the spec is? but it sounds a little low? Maybe squirt a little light oil in the plug hole and try it again? I think you said you were getting a weak spark from each plug? If all the wiring reads good with an ohm meter you may have bad ignition coils, but that may be a stretch?
Let us know what you find.
