Purpose of the compression release arrangement employed in the RD-19 series is as you know to reduce cranking effort when starting manually (not effective when starting electrically). To achieve maximum effect in this respect, the compression release valve, actuated by the "track" on the starter pulley, should open as early as possible when pulling on the starter cord grip, thus, a simple precaution should be exercised when replacing the cord.
Adjust length of cord (between the starter cord grip and knot at other end) to a position where dimension "A", Figure 1 is approximately 1"; or, to position where starter cord anchor falls between embossings starter head, Figure 2, when the starter cord grip comes to rest on its seat. This may be accomplished by adjusting the "loop" in the starter grip.
