The EMPI 43-5712 Pro-Sync offers a visual, meter-based approach to synchronization that works with both side-draft and down-draft carburetors. Supplied with two adapters, it fits a wide range of intake setups so you can sync multiple carbs using a single tool.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Pro-Sync make carburetor balancing simpler?\u003c\/h3\u003e\n\u003cp\u003eInstead of relying purely on vacuum gauges or guesswork, the Pro-Sync provides a straightforward visual readout that shows the relative airflow of each carburetor.
