It is commonly accepted that most Mopar V-8 engines respond to an air/fuel ratio somewhere between 12.5 to 13.2 parts air to every one part of fuel, or a ratio of 12.5:1 to 13.2:1, and being able ...

For the sake of simplicity in this story, we’re going to install a DLG-1 digital air/fuel ratio gauge, with an optional LC-2 Digital Wideband “Lambda” 02 Controller, into a carbureted 351W ...

But these sensors were designed to be accurate only around 14.7:1 air fuel ratio. Attempting to build a "gauge" that could accurately deliver air-fuel ratio around 12.5 to 13:1 was challenging and ...

Step 2: Crank the engine while your right foot pushes the accelerator pedal. Pushing the pedal allows more air to enter the combustion chamber and helps bring the air/fuel ratio back to the right mix.

We review the new Innovate Technology G2 air/fuel gauge kit for Ford Mustangs which includes an air/fuel gauge, a wideband oxygen sensor, a wideband controller, and engine-tuning software - 5.0 ...

It's a common bit of tuning advice that a too-lean air-fuel mix will make your engine overheat. ... or even just fiddled with a carburetor, ... the ideal air-fuel ratio is 14.7 parts air to one ...

While a carburetor allows you to adjust the air-fuel ratio, it’s more of a set-it-and-forget-it type of device. Fuel injection (or throttle-body injection in the case of KTM’s two-strokes) is ...

Air-cooled engines rely heavily on a proper tune to remain cool — especially the proper air-fuel ratio on a carbureted engine, which can sometime be set to an overly lean condition by the ...

This is a crude way to adjust the air-fuel ratio, and anyone with a carbureted engine can attest that it's hard to drive under load when the carb is choked. It's easy to stray too rich on the ...

A: The best method to check air-fuel ratios is with an AFR gauge. Tuning by ear or with a vacuum port are effective ways to determine running condition, but don’t actually read the air-fuel ratio.

Many people conclude that a carburetor simply dumps air and fuel into the engine when you depress the accelerator. That’s fair to say in general terms, but plenty of science goes into the operation.
