Review on ALAVENTE Carburetor For Ford 240 250 300 YF C1YF 6 Cylinder CIL Engine 1975-1982 D5TZ9510AG, Carb For Carter YF Type, Replace # RSC-300A 6307S 6054 6055 6-736 6056 6057 6058 6059, Automatic Choke by John Kennedy

Installed on a 1977 Bronco w/302. Had to make one small mod by swapping the power valve housing on the bottom of carb. Not a big deal. Linkage was perfect fit for the automatic C4. It came w/a new base gasket. Just bolted it on, fired it up and drove it- no other adjustments needed. Idle setting and air/fuel seemed good to go.Side note: If your car or truck has an original style A/C system think about buying an idle up Solenoid to give the RPM’s a little bump up when the compressor clutch kicks on and off at stop lights or drive thrus.
