Some of the common connections include: :*Fuel line/hose - ''Be especially careful with the fuel hose as it will spill some out.'' :*Vacuum advance hose :*PCV hose :*Brake booster hose :*Throttle linkage/cable: Held in place with a clip. :*Throttle return cable: Held in place with a small bolt and nut. :*Throttle return spring :*Divorced-choke coil- Unscrew from the intake manifold if applicable. :The carburetor is held in place by two long bolts visible on top of the air horn and either two nuts or two bolts on the back of the carburetor on top of the throttle cable bracket.
