Auto Parts Prodigy Carburetor Synchronizer Pro-Sync 1–30 kg/h Scale — Universal Accurate Airflow Meter

Auto Parts Prodigy Pro-Sync Carburetor Synchronizer is a universal airflow meter designed to quickly and accurately balance dual and multiple carburetors with a 1–30 kg/h scale.

Whether you're tuning a vintage VW, a dual-carb motorcycle, a trike, or any side-draft or down-draft setup, the Pro-Sync gives a clear, repeatable readout so you can equalize airflow across barrels. Built for hobbyists and professional mechanics alike, this tool removes guesswork from synchronization tasks and restores smooth idle, even throttle response, and consistent performance without restricting engine breathing.

How does the Pro-Sync make carburetor balancing more accurate?

The Pro-Sync measures actual airflow through each carb throat using a calibrated 1–30 kg/h scale so you see real-time differences instead of estimating by vacuum or sound. This direct airflow reading helps you match carburetor outputs precisely for consistent engine behavior across cylinders.

• Calibrated 1–30 kg/h scale for quantifiable comparisons
• Clear, bold markings for low-light visibility
• Zero airflow restriction design prevents altered readings
• Repeatable measurements for sequential tuning steps

Will this tool fit my motorcycle, VW, or trike carburetors?

The Pro-Sync was engineered as a universal synchronizer that adapts to both side-draft and down-draft carburetors commonly found on motorcycles, classic VWs, and custom trikes. A flexible hookup and straightforward mounting let you work across different throat diameters and configurations without specialized adapters.

• Universal fit for most dual and multi-carb setups
• Flexible hose and connector set for varied carb geometries
• Works on single, twin, triple, and quad carb arrangements
• Compatible with aftermarket and OEM carb models

How do I use the airflow meter during a sync procedure?

Attach the Pro-Sync to each carb throat one at a time, observe the airflow reading, then adjust the balancing screws or linkage until readings match across carbs. The device gives immediate feedback so you can make fine adjustments while the engine idles or at specified RPMs.

• Install hoses and secure meter to carb throat
• Start engine and let idle stabilize before reading
• Adjust sync screws until meter shows equal airflow
• Re-check at operating RPMs if required by service procedure

What features make this tool suitable for DIYers and pros?

Pro-Sync blends simple operation with shop-grade precision, offering an uncluttered gauge layout, durable construction, and airflow-neutral design. It’s lightweight enough for field work but robust for repeated garage use, giving both novice tuners and experienced mechanics confidence in their results.

• Easy-to-read, bold scale for quick decisions
• Sturdy materials built for workshop use
• Minimal setup so less time is spent prepping tools
• Portable size for roadside or garage tuning

Who is this for? If you maintain or restore carbureted vehicles—motorcycle owners, classic Volkswagen enthusiasts, trike builders, and professional mechanics—this tool simplifies achieving balanced throttle bodies without guesswork. Choose the Auto Parts Prodigy Pro-Sync when you want clear airflow data, durable construction, and a universal approach to carburetor synchronization that fits most common setups.
