lemming

I do not have the original "flat top" carbs. I replaced them with Holley carbs. As for the sticking choke, this is a possibility... I'm reading.

I have a '74 260Z (pre-fuel injection 280s), and sometimes when the engine gets warm, it will start to idle fast when I come to a stop light. To remedy the problem (until I come to a stop again) I can pull on the choke and then turn it off, and for whatever reason, the car will return to a normal idle. I got work done on the car about 1000 miles ago, and they said that one of the accelerator pedal hinges was worn out/installed incorrectly, so they drilled a new hole and so now I would get the full extent of the acceleration range. So yeah, that worked for about a week, and now it feels like it did before. Have any of you guys had this problem before? And if so, might you know a more permanent solution than what the auto body shop did? Thanks much!!!
