Latest Rage Deluxe Carburetor Airflow Meter Pro-Sync — Precision Carb Sync Tool, Universal Fit for Multiple Carbs

The Latest Rage Deluxe Carburetor Airflow Meter (Pro-Sync) is a visual, precision tool for balancing multiple carburetors to improve engine smoothness and throttle response.

If you work on dual or multiple carb setups—air-cooled VWs, dune buggies, motorcycles with side- or down-draft carbs, or vintage cars—the Latest Rage Pro-Sync gives a straightforward, accurate way to equalize airflow between barrels. It uses a clear graduated scale and is designed not to obstruct intake flow while providing repeatable readings so adjustments are faster and more reliable than guessing by ear.

How does the Pro-Sync show imbalance between carburetors?

The device uses a visible vane and a numbered 1–30 kg/h scale to indicate relative airflow through each carb throat. By reading corresponding positions for each cylinder bank, you can quickly see which carb is pulling more or less air and adjust the throttle linkage or idle screws accordingly.

• Visible vane movement gives immediate visual feedback.
• Numbered scale supports repeatable measurements (1–30 kg/h).
• Works with both side-draft and down-draft carburetors without altering flow.

Will using this tool affect engine performance while measuring?

No—the Pro-Sync is engineered to avoid restricting airflow, so readings reflect normal intake conditions. That means you can synchronize carbs at idle and light throttle without introducing measurement artifacts, helping you tune for real-world running behavior.

• Low intrusion design preserves authentic airflow dynamics.
• Fast readings let you make adjustments during normal idle or steady revs.
• Durable construction tolerates workshop use and repeated fittings.

What vehicles and carb setups can this synchronizer handle?

The Latest Rage Pro-Sync is a universal tool aimed at multiple-carb configurations: twin or triple carb setups on classic VW platforms, dune buggies, Karmann Ghias, VW buses, and many motorcycle trikes. It adapts to both side-draft and down-draft designs, so a wide range of small engines benefit from precise balancing.

• Compatible with dual and multiple carburetor arrangements.
• Suitable for side-draft and down-draft carb bodies alike.
• Commonly used on air-cooled VWs, custom buggies, and motorcycles.

How do I use the Pro-Sync for reliable tuning?

Mount the gauge to each carb throat in turn or use adapters to read pairs simultaneously, then note the vane positions on the numbered scale while the engine idles at a stable speed. Adjust linkage or idle screws until the readings match across all carbs and re-check under the same conditions to verify the balance.

• Attach the sensor at consistent throttle and RPM for each measurement.
• Make small adjustments and re-measure to converge readings.
• Document scale values to reproduce settings after maintenance.

Who this is for: The Deluxe Carburetor Airflow Meter from Latest Rage is aimed at home mechanics, restoration enthusiasts, and professional tuners who need a reliable, visual method to synchronize multiple carburetors. If you maintain classic VWs, custom buggies, or multi-carb motorcycles and want quicker, more accurate balancing without guesswork, this universal Pro-Sync tool is a practical addition to your workshop.
