It only spins easily by hand when the plugs are out.. otherwise it is a one-compression-at-a-time kind of exercise. Compression is normal.. I am well familiar with its feel. I am currently leaning toward a intermittent condition with my CAS wiring or the bad gas/flooding issue. At least it has made me think harder about my CAS as a single point failure and review the wiring. Thanks for all the suggestions.
