Hello
Ric2504You have probably already played with it but I guess the
obvious direction would be to screw the cable out from the
block that holds it - pushing the lever downward, and increasing
the spring tension, thus moving the jockey bearing outward.
Unfortunately, I do not have a manual for this model Morrison
or the Scott Bonnar 690 that also used this system.
