Changed the FCR acceleration pump diaphragm. Visual inspection is important. Changes in total discharge volume are difficult to understand...
I am trying to replace the FCR standard accelerator pump diaphragm with the Kawasaki KX250 diaphragm. There is a dot in the center of the accelerator pump that suppresses the movement of the accelerator pump diaphragm. As for how much of a change there is,you can feel the change when you see it for the first time.
