The carb throttle and magneto advance are not connected, and you
have to operate each one separate.
As Frank said, they have a plunger pump. I believe it’s operated off
of the drive shaft. I have two of the D1D’s, but no manuals.
I don’t have a good photo, but believe the water pump is
in the tin pie pan in my photo!
