Sorry it’s taken me so long to post a resolution to this problem. As colder weather has begun here in Illinois, and I found need to drive my 3200 numerous times, I was experiencing idle kick down problems and began the hunt for the cause. As I started with idle mixture screws and subsequent movement of the throttle linkage by hand, I noticed the linkage hanging up a bit. I initially thought the gas pedal rod through the firewall was binding a bit, but further investigation revealed the culprit. The bottom of the accelerator rod lever was touching the firewall. I adjusted the accelerator rod length at the carburetor and subsequently reduced engine idle and all problems solved. Thanks for you interest, help, and patience!
