Just a thought, if you had the servo for some time it might need to be serviced, it can collect a lot of dirt inside.
The spektrum servo is waterproof, and apparently dust proof. I opened it up and no dust
I got for S&G's a Dynamite Throttle Return Spring. For $2.45, its a no brainer. If it doesnt work the way it was intended to work, I'll try to retrofit it. Like I said, for under $3 bucks, doesn't hurt to try!
