Ron,
I had problems initially with insufficient assistance from the bungee.
I recommend you should first check that the assembly moves freely at the
correct torque for the bronze bearing bolts.
I then found that I needed 17 "Falls" before retraction was sufficiently
assisted and 18 was slightly too strong in that gear extension was starting
to become difficult.
Perhaps other builders with more experience could offer comment but I am
convinced that the pre-requisite is a correctly fitting and free moving
pair of bearings.
