I would take it that the blocking off of the heat riser would not have caused the carb to run richer.

If by "heat riser" you mean the tube that is located on the lower part of the intake.
Blocking that tube will prevent hot air from reaching the heated element in the automatic choke as it should. This will cause the choke to stay closed longer than it should and thus, run rich.
