I installed a holley 4 barrel carburetor in my 1983 buick regal , but it starts fine but won't idle ?


Check your vacuum hoses. Holley aftermarket may not have as many vacuum ports as OEM QuadraJets, and you may have a vacuum line that isn't plugged into anything...or you may have a vacuum leak around the carb base gasket. Also, does the Holley have an electric or manual choke? Is it connected?

I have a gmc truck with a 351E v6 it will not idle there is a line opening on the back of the carb plate and a small line that comes off of the left side of the carb. Where do those lines go to? It is not...


I don't have a diagram but I think the replacement carburetor may have come off an engine that had a governor which was activated by a plunger under the distributor plate. The vacuum lines went between the carburetor and distributor. Check to see if there is vacuum at one of the lines when the engine is runnuing. If there is just plug it off. A vacuum leak could be causing your idle problem.

I have a 1988 buick electra w/ 3.8 v6 engine. It runs but will not idle, has the sound of a large vacuum leak which i can't find. Have check all vacuum lines and have replaced the vacuum bypass solenoid as...


Get A can of WD40; look for the flammable kind. Start the engine and spray around the manifold and any vacuum hoses you see, work your way from top down, when you get close to a vacuum leak the engine will give you an indication as it changes the speed and sound. Then look closer to identify the location of what is leaking. Hope this helps fixya up.

I purchased a F250 that has a 460 engine/ 4 barrel carb system in it. Do you have any suggestions on getting better gas mileage?


Tune ups on a regular basis are a must. A couple times a year check the plugs and replace if they are a little bit dirty. Also air filter. Keep the carb in tip top shape, tuned and rebuilt as necessary. Install an aftermarket vacuum guage in the dash where it is easily readable. They come marked with ranges to indicate good or poor mileage. It just plugs into the vacuum lines on the intake or carb. The more you keep it in the good range the better the mileage. Driving habits will be your best bet,keeping off the 4 barrel. Hope this helps.

I need to adjust a carberater and get the 4 barrel to start working


Most likely you have a Holley carb. You may have a 460 engine. If you have the carb with a big vacuum pot in front of the carb, then you have a RPM governor. The RPM governor will work against the 4 barrel.

The main mixture for the idle jets can be adjusted like any old style carb. You may have plastic caps over the idle screws but take them off. Then use a vacuum gauge on any intake fitting and proceed to read the vacuum level as you turn the mixture screws. You want the mixture to reach a maximum RPM, then evenly turn the screw in until the RPM drops slighty and then balance for smoothest idle.

After this step adjust curb idle and see if this helps when the 4 barrel kicks in. Holley has different springs for the vacuum actuated secondaries and they are color coded. If the carb is original it should be right, but if the carb is of unknown origin you can check the proper vacuum spring, main jet, power valve and so on in a good Holley book. The mechanical secondaries are also listed with clearances to hand adjust.

By adjusting the mixture screws you have set the engine to idle just below peak vacuum pressure. This means you should have more vacuum to work the secondaries.

1974 corvette 4 barrel secondary will not kick in. How and where do the vacuum lines run to make it work? Vacuum diagram would really help. Thanks


The secondary operates via mechanical linkage, look around on the carb for linkage that has become disconnected
