with recoil > string goes back into engine casing on starting for next time
with-out string comes off of the flywheel & your left holding it
i have one of the latter i dont use, just keep it for the 3rd reserve engine
When do you want it and how much you want to pay. I have one and a elderly Zodiac 260 (slats) that I am replacing before start of season but will not be able to install my davits until april (They are needed for replacement tender).
