Looking at the first picture, as far as I can determine, it appears the 'flat' area that would push on the pulley has wrapped under a bit of non-flat spring. Following with eyes, from the flat end of the spring, clockwise, it goes from butt-end, round, to flat at about 1 o'clock, continuing flat until 11 o'clock, when the flat area ducks under the butt round end of the spring. That does not look right. I figure the spring got tired, wore too much, and failed. If there was internal wear of the other parts, the shift in load, from 'driving - to move' to 'coasting- where power is returned the opposite direction, trying to turn the crankshaft, may have allowed internal parts to move around, and caught the spring between a rock and a hard spot. Were other parts worn? Was there a flat on the 'spiral' or 'ramp' area, or the pins that ride on the ramps? If there was a worn spot, it could have caused the pins to want to stay in place, rather than allowing the sides of the pulley to move in or out. I'd look at all the other parts for wear patterns, grooves, flat spots, and 'gulleys' such as at either end of the pins travel. If you find wear, you might consider replacement. tom

Grumpyunk I thought that too at first, kind of a optical illusion. I moved the first photo to desktop and zoomed in. The spring end is in the center of the nest. The spring wire end is at about the 10'clock position and goes CCW. At the 12'clock position the wire transitions from flat, missing paint, spring end to round. More CCW and the wire completes one round and goes under wire end. A noticeable amount of scratching at the spring end.
I'm not sure what connection point is even supposed to be moving in this design.
1. There is the spring sitting on a cup at each end. Should the spring turn on one or both of the cups? 2. Should one or both of the cups turn against their mounting position? On mine the outer cup (closest to the nut) showed no sign of rubbing against the clutch. The inner cup is mounted against the two lubed up oring seals. That would seem to be the most obvious rub point but mine is quite tight at removal. Don't know.
