You WILL NOT REGRET getting your carbs done by Ztherapy. Not one bit. Really improved my mid and upper RPM,a swell as gave me a rock solid idle. The video spells out exactly how to use the car sync tool. After you get the carbs hooked up double check all your vacuum lines are good. The new SU's are so tight, they respond to the slightest adjustment. Make sure all the vacuum lines are pristine so you give yourself a fighting chance to get those carbs dialed in. I think it took me about 5 minutes to do the job once the engine was warm. After I drive it a few months, I will probably just do a double check, but watch the video several times, and get acquainted with every adjustment screw and its location, it will become like second nature after a while. PS.. I have to add this, DO NOT forget to remove your fuel bowl vent caps... haha
