I captured 2 videos for you to see the problem with the throttle return spring. Video 1 shows the failure of the throttle return spring to close the carb if the kit goes out of electricity, and the second video shows the throttle return spring replaced with 2 Goody Ouchless rubber bands capable of closing the carb, but then the servo hasn't enough power to open the carb fully. Please take a look at the videos for me (link below). I need a new servo, right?
P.s. I told you before I had to rotate the carb to being able to access the low speed needle, but then the servo wouldn't have a straight pull. I have now rotated the carb back so the throttle servo has a straight pull.
