620 doesn’t want to stay on (when) cold


Recommended Posts

I have a 1972 datsun 620 with an L16 engine that doesn’t want to stay on when it’s cold. I have to press the gas pedal for couple of minutes until it warm up that’s when it stays on.  I’ve replaced  the original carburetor with a Weber carburetor with electric choke. also replace the point with a pertronix electronic ignition. If you guys have any ideas what could it be. I would appreciate it.

The Z24 in the '83 720, also probably the last Nissan carbureted vehicle, has the choke set at the factory and the 3 screws are replaced by rivets so the owner can't tamper with it. I drilled mine out and used self tapping screws.

Cool, is there anything online that shows you how to adjust the carburetor.
