The synchronizer measures the airflow entering the carburetor intake. Compare the readings between carburetors and make the appropriate adjustment according to the engine and carburetor manufacturer's specifications.
This makes it easier to identify airflow differences and achieve a more balanced multi-carburetor setup.
Warm the engine according to the applicable service procedure.
Position the synchronizer securely over the compatible carburetor intake.
Check the airflow reading.
Repeat the measurement on the other carburetors.
Adjust the carburetor linkage or idle settings as required.
Recheck the airflow readings after adjustment.
Always follow the correct tuning procedure for your specific engine and carburetor configuration.
