Today I took the 47 DeSoto for a neighborhood drive. Seemed OK under 25 mph. Took it on the main road, and it upshifted but bogged down. Back in the garage, could not get it to rev. Bogs down, tries to rev but slows down, lup lup lup.
DeSoto Convention 4 weeks away! Carburetor suspected. I'll remove the top and check the step-up piston and look for anything out of place. The shop manual says, if there are any problems, rebuild the carburetor. Wah. I got a Carburetor Exchange in 2015, 8 years ago. Maybe better than trying to rebuild it myself. Thoughts? Sympathies?
