I inherited a 1957 Ranchero with a 312 Y-block. I'm having troubles getting it to run right. Put on a new distributor cap, cleaned the points and rotor, cleaned the plugs, new plug wires, set the dwell, and new fuel filter from the pump to the carburetor. The idle is good but it wants to slightly stall when I give it gas from a stop and then erratically cuts out. I tried to set the timing but the distributor is locked in. I have tried wd40 and PB blaster for a week. The only modification I can find is the original carburetor.
