Corolla XL 1994 Model Hard Starting

Ah, carburetor.
Let the engine get fully cold (3+) hours, and remove the air cleaner assembly and look at the choke plate. If it is fully open, then it is stuck. This could be due to grime or a faulty thermo servo (or even electric, depending on the car ... manual chokes went bye bye in the 60s and 70s and everthing was either electric or thermo spring).
If it is partly closed like it should be, check the fuel bowl, make sure it still has fuel in it. If it doesn't have fuel in it, then the seal for the accelerator pump has a leak, and it is causing the fuel bowl to empty out between starts.
Usually the above two are what cause hard start conditions while everything else is running fine (and since you only mentioned hard starting, I'm assuming that the idle and everything else is perfect the way it is).
