To all Aspen owners, do you remember driving home in the rain making all right turns because you were afraid you might stall out in front of traffic if you made a left.
It would stall even if it was just humid. Something to do with the carburetor engineering.

That little 1-barrel carb was the victim of the need to satisfy environmental concerns in an era before fuel injection became available. By this time, Mopar was almost bankrupt, and didn’t have the R&D budget to further refine the product, nor the resources to simply install a good Holly Economaster.
Most American cars of the era featured a bundle of snakes on top of the motor, as a maze of vacuum and air hoses tried to keep the thing within specs. Most exasperated redneck shade tree mechanics removed the “pollution junk”, installed a good Holly carb, bought an adapter so they could fill up with leaded fuel, and replaced that catalytic converter with a “test pipe.” There... problem fixed.
My aunt had a LeBaron of about the same period that used to stall in wet weather. It had a detuned version of the 440 Wedge engine. My cousin and I found a wrecked Road Runner and pulled the ignition and intake parts off and put 'em in the LeBaron... no more problems. The Chrysler "Lean Burn" hardware was the source of the trouble, I believe.
