Depends if you are using an analog or digital meter. Zero could mean "no continuity" on one meter (that's bad when you are checking a copper coil for conductivity) or "great", nothing is creating any resistance and the coil is 100% intact.
Ohm's tests only really give you an indication of 1) it's scrap or 2) it needs a DVA test.
The resistance, if any is present, will change significantly just due to the air temperature or the temperature of the stator. A cracked coil may have a perfect ohm reading when cold and then when the copper expands due to heat it loses continuity all together when the windings expand and "move away" from each other (or squish together in other cases).
If you look at the specs for the CDI stator they may tell you at "what temperature" you should see those specs.
Here is an example of the warning from Merc -
Resistance varies greatly with temperature.
Measurements should be taken with an ambient temperature
range of 65 to 85 F
