Bavaria & 3.0 CS

  1. Ensure engine is at normal operating temperature. Remove air filter and check ignition timing and dwell angle. Connect exhaust gas analyzer, tachometer and carburetor synchronizer to vehicle.
  2. Before synchronizing carburetors, adjust CO% level to 2 percent. If uncorrected idle does not exceed 1000 RPM, CO% level should be reduced. Using synchronizer, adjust by-pass adjustment screw on both carburetors to obtain an equal airflow. DO NOT alter setting of first stage throttle plate.
  3. Adjust idle mixture to specifications at each exhaust manifold. Each manifold has an opening for sampling exhaust gases, which is covered by a copper bolt.
  4. Reinstall air cleaner and adjust mixture to lean best idle at specified CO% level. Check idle CO% level at tailpipe once more. Disconnect vacuum hose from dashpot.
  5. Operate throttle linkage to increase speed to 2500 RPM, then gradually decrease throttle opening until dashpot set screw is contacted. Speed at this point should be 1650-1700 RPM. If necessary, loosen dashpot clamp and turn dashpot to obtain correct RPM setting.
