Does the pump flat push rod on the 1920 have a sleeve and ball
like the round type push rod.

No.

Thanks for your reply.
I am working off a generic parts diagram.
Comparing actual parts when stripping down
the Carby. The other issues I have are l did
not find a pump diaphragm conical spring
between diaphragm assembley and main well.
Also when taking the pump diaphragm out
I have a lone loose ball that came out.
I can see other balls in their correct places.
