Do you need a bigger carburetor for street performance?
If you are building a street performance engine, you may need an emissions legal carburetor such as this Carter AFB. It’s true that a carburetor with larger throttle bores will flow more cubic feet per minute (CFM) than a carburetor with smaller bores. More airflow means more horsepower, but mostly at higher engine speeds.
What should the air / fuel ratio be in a carburetor?
Consequently, mechanical carburetors require constant fiddling and readjusting for prevailing weather conditions and track conditions. For peak power, most engines like an air/fuel ratio of 12.8 to 13.2.
What did I do to my 1992 Ford 460?
Just installed the Twisted smog box with all the smog elimination hardware on my 1992 F-250 460.

What should I do when I Change my carburetor?

While carburetors are not really considered commonplace anymore, for many decades they were the preferred method for fuel delivery, and working with them was a much more common occurrence.
How do you adjust the fuel mixture in a carburetor?
Once the engine has arrived at operating temperature, go back to the carburetor and adjust the air fuel mixture screw, or screws. Tightening the screw increases the amount of fuel, while loosening decreases the amount of fuel. When making any adjustments, it is also important to make them in small increments of a quarter turn.
Is it normal for a carburetor to hard start?
The hard starting just doesn’t seem right after sitting for only a couple of days in the garage. Thanks for the help. That isn’t a problem. It is normal. The gas evaporates from the carb, and you need to crank the engine long enough to get fuel from the gas tank which is about 15 feet away from the engine and below it.
