Throttle won't close after fitting heated grips

I was running a cable from the battery to my tomtom cradle today and I though since
I am under there I'll fit my heated grips (the irony of fitting heated grips when summer
is approching is not lost on me). The problem occured with the throttle grip, I fitted it
with the super glue as instructed and then went to run the cable under the tank. Once it
was all back together I tried it and the throttle wouldn't snap back into position it remained
open and it was a bit stiff to turn, I removed the grip using brake and carb cleaner again
and tried it with out the grip on it and it still doesn't snap back though it is easier to open
up now. I am not entirely sure whats wrong with it at first I assumed that it might be some
super glue squidged out the end in glued the plastic sheath underneath in place but i don't
know if this is possible or likely?

So I am a bit humped as ride it when the throttle won't close so any suggestions welcomed.
