After I flushed my radiator, not only does the radiator now leak but for some reason (and it might not be related) the car won't hold an idle.

Any time I let go of the choke, the engine just dies, and with the choke all the way out the car sits at around 1K RPM. With the choke all the way out, it feels as if the car is jerking around in rhythmic patterns, too. I fear I may have a blown rotor? Maybe worse? No idea. Can't think straight.

Anyone have any ideas?

 

Is it possible that mabey you hit something on the carb when fiddling in the engine bay? Mabey you hit the distributer and knocked the timing off.

 

it sounds like you have a large vac leak, verify with air cleaner lead off smothe carb throat with red rag, if it speeds up its suckin air
