I had a non correct throttle return spring on my car that I finally got around to changing out for a correct reproduction by Mansfield Restoration in Massachusetts. I threw out my old spring as it was "weak" and not correct. I hate my new spring. The old "weak" spring allowed me to feather the gas and gave me a lot of control. The new reproduction correct spring is tight and unforgiving. Should I try a different spring from another company or are all the reproduction springs this way, ie tight?
