Symptoms
Stumbling or stalling cold or hot, hard hot starts, rich running, fuel smell.
The fix, step by step
- Rule out vacuum leaks and ignition faults first.
- Rebuild with the kit for your year and engine: the V8 two-barrel kit is listed for 1981–91 and the 4.2 kit for 1982–86.
- Fit a new base gasket and insulator, set the float and choke pull-off to the kit spec, and check timing with a light.
- Throttle-body injection replaces the carburetor and needs its own pump, return line and wiring; it's the most common long-term fix.
