Carburator Question

Accelerator pump diaphragm. Should any fuel pass the diaphragm. End cap had fuel in it.
Hard to start and hesitates when accelerating from idle. Distributor, points and coil all good. New plugs. 1952 M38 YS carburator.

Thanks
Scott

What is the physical condition of your accelerator pump diaphragm?

This is the correct assembly drawing

Everything looked correct. To rips or cracks.

It’s leaking somewhere. Took carb apart and cleaned everything. Would idle but nothing more than idle
