* Rich While Driving:
Reduce size of main jets, lower float levels, use smaller number power valve, and reset throttle plates.
* Rich At Idle:
Reset throttle plates, tighten idle-mixture screws, lower float levels, reduce fuel pressure, clean air bleeds, use smaller number power valve, and increase initial ignition timing.
* Runs After Shutoff:
Reset throttle plates, lower idle speed, and check ignition timing.
* Sluggish At Fully Open Throttle:
Decrease size of main jets, lower float levels, and reduce fuel pressure.
* Smells Rich At Idle:Reset throttle plates, tighten idle-mixture screws, lower float levels, reduce fuel pressure, clean air bleeds, use smaller number power valve, increase initial ignition timing.
* Smokes At Idle:Reset throttle plates, tighten idle-mixture screws, lower float levels, reduce fuel pressure, clean air bleeds, use smaller number power valve, and increase initial ignition timing.
* Smokes Under Acceleration:Decrease size of accelerator-pump nozzles, lower float levels, reduce fuel pressure, and reset throttle plates.
* Hesitates Under Light Acceleration:Reset throttle plates, raise float levels, and reset idle-mixture screws.
* Hesitates Under Hard Acceleration:Increase size of accelerator-pump nozzles, reset throttle plates, and raise float levels.
* Surges At Idle:Reset throttle plates, loosen idle-mixture screws, and raise float levels.
* Surges At Cruise:Reset throttle plates, raise float levels, loosen idle-mixture screws, install larger main jets, and install higher number power valve.
* Won't Idle Down:Reset throttle plates, check idle-mixture screws, lower float levels, check initial timing, check throttle linkage, and check for vacuum leaks.
* Won't Stay Running Below 1500 Rpm:Reset throttle plates, check idle-mixture screws, lower float levels, and check initial timing.
* Won't Start:Prime carb with fuel, squirt accelerator pump, check float level, and check ignition system.
* Won't Stay Running:Reset throttle plates, check idle-mixture screws, lower float levels, and check initial ignition timing.
