Perfectly Syncing A Carbureted Engine 🏁

Autos and Vehicles

Original Video Credit: IG/datsun_tokyo A mechanic uses an STE Synchrometer to measure airflow through the velocity stacks of a multi carburetor engine. The tool is placed directly over each intake to compare how much air every carburetor is pulling at idle. If one carburetor flows more or less air than the others, the engine can run rough, hesitate, or idle unevenly. By carefully adjusting each throttle plate until all readings match, the mechanic synchronizes the entire intake system for smoother operation and more balanced performance. Multi carburetor setups like this were common on vintage sports cars, motorcycles, and racing engines before modern electronic fuel injection became standard. Even today, proper carb synchronization is still critical for getting these engines to run correctly. No copyright infringement intended. Content is shared for educational purposes only.

I didn't see alignment. I saw a needle pointing at different places on the scale.

This is only syncing idle airflow , nothing more

The last one is off.

That’s bullshit, you want them to be in sync at full throttle. Measuring at idle gives you zero information

Easier with a piece of pipe and your ear. This is good if you're deaf though.
