The bike dies when giving it throttle and I have been working through the carbs and the FSM. Set my float height and went to do the measurements for the accelerator pump. The rod rests on the control arm when the spring is out. With the spring in it is 0.5mm from the arm. When opening full throttle the arm stops just short of contacting the pump rod bottoming out on the idle adjustment housing notch. The book says to “bend the adjustment arm” to get between 0 and 0.4mm clearance between the rod and the arm. It then says to measure the gap between the control arm and the idle screw housing stop. This is a 79 and I’m not sure if it is an issue with the rod spring, the adjustment, or both. This is a rebuild kit. The old diaphragm was shredded.
The picture is black and O have read elsewhere to never touch the accelerator pump adjustment, but that was for the SOHC so I’m not sure.
