I worked in chrysler dealerships for years back in the era, and thermoquads have a tendency to warp the plastic fuel bowls. Especially if the screws work loose. I'v replaced a lot of fuel bowls on these over the years. I remember it was a big problem with the lean-burn era cars, ( cordobas etc.) Many times you can sand them flat if there not warped bad, but that usally not the case. Most of the time the idiling problems come from two small round gaskets down in the fuel bowl that leak. I just rebuilt the one on my Lil red express, as they were leaking. Runs great now.
