Carburetor Float Sync Tool SU 240Z

Part # : 800-842
New Flaot Sync tool for SU carburetors.

New Flaot Sync tool for SU carburetors.  Setting float levels in your Datsun 240Z SU carburetors is critical to optimal engine performance. Power and fuel economy are sacrificed if float levels are set too high, too low, or differ in each bowl. Until now, there hasn’t been a tool allowing you to visually inspect both float levels at the same time, with the engine running. Float-Sync shows you precisely where your floats are set to ensure your engine is running with peak power and efficiency.

The level of fuel in the float bowl dictates the level of fuel in the jet nozzle. This is a big deal for SU carburetors because the fuel level in the jet nozzle directly impacts engine performance. When the engine is running, a vacuum is created in the SU carburetor venturi that pulls fuel out of the jet nozzle, mixing it with air and drawing it into the engine. If float levels are adjusted too high, fuel puddles at the top of the jet, allowing too much to be drawn into the engine, creating a rich condition. If the float is adjusted too low, it will be harder to pull fuel out of the jet, creating a lean condition.

A rich condition can cause plug fouling, poor fuel economy, gas fumes, diluted crankcase oil (contributing to blow by and reduced engine protection), and in extreme cases potential for an engine fire. A lean condition can cause the engine to stumble, back-fire, ping and run hotter than it should, creating the potential to burn valves.

You will never wonder again how your floats are adjusted. Only Float-Sync allows you to see precisely where your floats are. You are able to see the fuel level, with the engine running, throughout the entire RPM range… all without opening the float bowls. 

Installation instructions included.
