OK, I made sure the idle transfer slot is not covered up, but the problem persists. I noticed that if I open the choke valve even a little it dies. Does that indicate a vacuum leak? Or something else?
Thank you.
I haven't been able to get it to idle. I tried backing off the idle air mix screws a whole bunch but that didn't help. What you say makes sense because the primary valves are completely closed when you let off the throttle. Would that cause it to die at idle?
Thanks for your help on this.
I have a 1979 Dodge half-ton 4 wheel drive pickup with an automatic transmission, a 360 CID engine and a thermoquad carburetor (No. 9225). I bought a used carb and put it on and it won't idle. I rebuilt the carb and reinstalled it and it still won't idle. I've tried backing out the idle...
