Springs are fairly simple, if you wind it tighter it will give more resistance. If the mechanism for the securing of this spring holds both ends in place keeping the "re-wind" intact then you will get a change in resistance, if it does not then you will not. Other carbs like the FCRs I used can be tweaked in this manner or the spring itself can be replaced with one of a different resistance.
Are you sure this spring is your problem? I ask because in the 10 years this forum has been online I've not seen anyone else cite a need to repair, replace, or rewind it and there are other possible reasons for malfunctioning carbs.
Photobucket is trash now, use something else.
