The adjusters should go in just far enough so they can hold a little tension on the motor (if u keep turning u r spreading the frame apart)
Leaving the nut loose would cause trouble.
Looking at the pics the adjuster is in to far u need to back both of them off and start over.
This is only what i would do if i did not have the torque wrench.
I would turn it in till it seats then turn in 1/4 to 1/2 turn.
On mine the estimated space between the casel nut and the bolt that goes thru the frame is .200 to .250 (do not have my calipers at home.
