Default Dumb Quadrajet Secondary Venturi question

Hi Folks,

If I want to check if my secondaries are operating properly, can't I do this while the engine is idling, by turning the secondary throttle plate instead of the primaries? Should I get smooth throttle with just the secondaries?

Right now the primaries seem to work fiine, but the secondaries choke and sputter if I hold 'em open, say, 1/4 or 1/2 way or so (independent of the primaries.)

Seems to me the fuel mixture should be the same on the secondaries, so I should be able to move either of them and get a smooth throttle.

If I'm on the road and I open 'em up, the car hesitates pretty bad. If I'm at high RPM it seems to work fine.

I'm not sure, but the secondaries shouldn't kill the engine like that, should they? Or am I just supposed to be careful when I open them up.

??

Thanks
-Jim
