Checked all vacuum lines. Routed and secure. Some are super old but when hit with brake clean, engine does not Rev up. I did have some gunk gas in it but the Jets are squirting clear. When I first completed the swap car idled perfect cold or hot but would not rev without breading up. Did plugs wires cap rotor and coil, set timing and idle. Drove it for about a mile or so then this situation started to happen. My dad asked a good question just now. How about the distributer?
