    Moor loops decreases the tension. On some outboards the pawls could drag at a slow idle. The extra turn decreased the tension so the pawls would extend at a slower speed. Of course heavier wire increases tension. – about those old “Simplex” auto rewind starters. – Because of minor variations in sand castings and the fact that the hole a screw goes into must be slightly larger than the screw, the hole in the starter housing is larger than the shaft of the spindle that holds the rope pull in place. This allows the bully to be centered over the crankshaft with a 3/16″ rod. Most starter damage happens when the housing is tightened with the projections on the rope pull pressing on the pawls. The pawls are always extended at rest. So when replacing a starter housing, first pull out the rope. When the housing is resting lightly on the pawls, allow the rope to retort and the projections will drop into place when they slide off the pawls. Then of course the pulley must be centered before the screws are tightened.
