This is one of main contributing factors to a rough idle or no idle. You may have noticed after a careful examination of the looseness of throttle shaft that in most cases will be on the throttle cable side if not both sides of the throttle plate.  The cable side of the throttle plate “bushing” receives the most stress thereby causing critical ware in the aluminum throttle plate resulting in vacuum leak. The throttle plate contains no factory “bushings” of any kind as the hardened throttle shaft after only a few years of use simply wares away the softer aluminum material.  However if your Quadrajet carburetor has other problems you may NOT notice the benefit of the Barker Bushings© kit, so additional repairs maybe needed to your Quadrajet such as the fuel float bowl and air horn assemblies because they are more than likely warped to some degree.  Even if you choose to have me rebuild your Quadrajet or any other carburetor, there may be other issues to factor in such as the condition of the application motor, ignition, cooling systems or other as of yet undiscover problems you may have. If you choose to do your own carburetor overhaul, it is highly recommended that the Rochester Quadrajet you're intending to install the Barker Bushings© kit into be thoroughly cleaned. The best recommendation would be to install this Barker Bushings© kit in conjunction with the use of the Barker Gang Garage Quadrajet Un-warping© service. Or we can we install the Barker Bushings©, unwarp your Quadrajet for you.  Call for pricing.  Some warranties may not apply. Please beware of inferior throttle shaft bushings as many companies make more expensive bushings or make them out brass, copper or even bronze claim to have the ultimate bushing. Their kits are price much higher and these materials are no match for my supper stainless steel with 7% impregnated lead.  These Barker Bushings© are guaranteed1 for the life of the carburetor and will outlast and outperform any other bushing material period !! In the 45 plus years I, Dennis Barker have been un-warping Quadrajet carburetors using my propriety process and un-warping tool that it has been my experience that most EVERY Quadrajet carburetor is warped to some degree and the throttle plate “bushings” are out of round and worn out due to the stress of hard acceleration or years of use with particular ware to the throttle cable side “bushing”. One of the most common byproducts of a warped Quadrajet is the loss of vacuum to the power piston.  The power piston vacuum circuit located between the fuel float bowl and the throttle shaft plate.  When the fuel float bowl is warped, the thick gasket looses its sealing properties due the warping effect thus resulting in loss of vacuum to the power piston which results in poor performance and poor gas mileage.  All of these contributing factors add up to what is known as the dreaded Quadrajet bog, rough idle or no idle. My stainless steel Barker Bushings© can be used to rebush almost any carburetor that has a 5/16s throttle shaft.  We can also rebuild any type of carburetor for any application.
