I looked it up and you have the same solenoid and set-up as mine.
The solenoid is not adjustable, make sure that all the parts move freely, Does the cable stop pull freely or does it stick, make sure that part 110 slides on the cable freely?.
How much slack is there between the stop cam (40) and the solenoid, if it's too much you might need a new cam or put a piece of tubeing over the solenoid pin to take up the slack.
EDIT: Glad you got it working!
