I am getting some off idle hesitation under heavy throttle which I believe is due to the accelerator pump not engaging properly.
I checked the instructions for how to adjust the spring but my accelerator arm lever has no pressure to apply upwards. The carb is new and I checked the diaphragm and saw no cracks/tears/rips.
Any suggestions. If I remove the slack between the arm and the throttle cam lever, the pump is close to bottom out already. The accelerator arm basically doesn't push back.
Edit: Figured it out, the diaphragm is missing the internal return spring from the factory...
