I think that if you had the correct spring, you would not have needed to rough up the pulley to make it work.
I have never adjusted a motor by bending the bracket. I have always been able to make fine adjustments by grabbing the end of the string next to the lightly crimped eyelet with a pair of pliers (edge resting against the eyelet) and twisting the pliers just a bit to tighten further.
The string can also be loosened this way if the crimp isn't too tight.
When adjusted, tighten up the crimp.
I suspect your comment is spot on regarding having the correct spring. I will know in a couple of days when a correct spring arrives.
I like your technique for adjusting string tension. Unfortunately as a youth, I must have performed indelicate surgery on the crimp - it was a wee bit mangled, and a knot seemed to be the easier solution.
