ARE WEBER CARBURETORS EMISSIONS / STREET LEGAL?
Aftermarket carburetors sold in the USA are not considered emissions or street legal. The only carburetor considered emissions legal is the original carburetor installed on the car from the factory.
WILL INSTALLING A WEBER CARBURETOR IMPROVE MY FUEL ECONOMY?
The majority of the progressive carburetor kit applications do improve fuel economy and driveability. IDF & synchronous carburetor kits are designed to increase performance.
MY CARBURETOR IS RUNNING RICH AND I CANNOT GET A FUEL MIXTURE SCREW ADJUSTMENT?
Check your fuel pressure. It should not
exceed 3.5 psi. High altitudes will cause a carburetor to run rich. You should re-jet the carburetor with leaner jets.
WHY IS IT THAT WHEN I GO UP A STEEP INCLINE MY VEHICLE STALLS AND IS VERY HARD TO RESTART?
Make sure your fuel
pressure is 3.5 psi max., that there is no debris in needle and seat valve and insure that the float level is properly set.
WHILE DRIVING AT HIGHWAY SPEEDS MY CAR TENDS TO SURGE-HOW CAN THIS BE FIXED?
Check the fuel pressure, if too low & not enough volume, check the fuel pump and fuel filter. If the carburetor is running too lean, the carburetor should be re-jetted.
MY VEHICLE HAS A FUEL RETURN LINE. DO I HAVE TO DISCONNECT IT?
Please check fuel the pressure first. The fuel return line should be disconnected only if pressure is below 2psi.
AFTER INSTALLING MY WEBER CARBURETOR, MY AUTOMATIC TRANSMISSION DOES NOT SHIFT PROPERLY?
You should check the linkage and the automatic
linkage adjustment.
IS THE AIR FILTER PROVIDED WASHABLE AND/OR CAN I OIL IT LIKE A K & N?
Yes, our air filter elements are
washable. K&N filters are also offered on our site as an option to purchase.
WHEN I BRAKE HARD OR MAKE A SHARP TURN, MY VEHICLE STALLS OR HESITATES?
Make sure the fuel pressure is no more than 3.5 psi max. Eliminate any
debris in needle and seat vale and check that the float level is correctly set.
AFTER INSTALLING MY WEBER CARBURETOR, MY CAR HAS A WHISTLING NOISE FROM THE CARBURETOR?
Check for vacuum
leaks, damaged gaskets or a cracked adapter plate.
AFTER SHUTTING OFF MY VEHICLE FOR 10 OR 15 MINUTES, I HAVE A HARD TIME RESTARTING-WHAT SHOULD I DO?
The fuel pressure needs to be checked. Also make sure that the float level is correctly set.
WHY IS IT THAT MY EXHAUST MANIFOLD IS GLOWING BRIGHT ORANGE AND MY TEMPERATURE GAUGE IS RUNNING HOTTER THAN USUAL?
Your carburetor is running too lean. Please check the fuel pressure. On modified
engines you should re-jet the carburetor.
