The Zen often uses a wax-element or bi-metallic automatic choke. If your car guzzles fuel but runs fine when hot, your choke is stuck.
Manual fix: The service manual suggests checking the "PTC heater" (a ceramic heater on the choke housing). If it fails, the choke never opens. In an emergency, you can wire the choke flap open manually, but you'll have to baby the throttle for 5 minutes every morning.
Do not start servicing without these. The Zen carburetor is small; forcing the wrong tool will strip brass jets.
