Carburator Question

Scott21 · Posted: Thu Jul 22, 2021 9:33 pm Post subject: 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
