Holley 4150 way to high idle.

Hi folks i need some help with my carb.

Car is a 1971 dart 318.
I just removed the dizzy to fab new kickdown linkage (not hooked up) and now I have an insane high idle, like 2,000 Rpm high (no tach).

Curb idle screw is not even touching the cam.
no matter how much timing I pull out I cant get a good idle?

Timing is around 8 BDTC but to even get where it dosnet sound like my engine is gonna blow Im at @ 10ADTC.

I have sprayed the carb with eletric parts cleaner and found no air leaks.

Both main and secondary butterflys are closed. I cant understand how with all the blades FULLY closed it can even pull that much air?

I just rebuilt the carb and it was working fine before I pulled the kickdown linkage and Dizzy.

It dose look like a lot of fuel is dumping out of the primary discarge nozzles but I never looked before so I dont have a base line to truly judge off.

Thanks for any and all ideas.
