Cold start valve or thermal time switch would be my first guess.
The CSV is used to provide that extra shot of fuel while cranking to allow car to 'catch'. It's controlled by thermal time switch (sensor on coolant pipe with brown Bosch connector). If the thermal time switch is stuck on the car will be hard to start warm and will tend to flood.
If the CSV or TTS aren't working at all it will be hard to start except from hot start.
If it hard to start even when fully warm, besides checking the above; check connections on starter and ignition coil and ballast resistors (if you have them). I don't recall exactly how the point type ignition handles ballast resistors during cranking; the solid state system bypasses one of them to compensate for battery sag and still provide hot spark.
