Well I've got the 1961 Ranchero running with the 144 installed from the 1962 Ranchero. It's enough to go short distances but running rough, with intermittent misfiring. Fortunately the temp gauge is working to warn me before the overheating gets dangerous or scary. I can get to town and back but wouldn't dare try an extended drive without planned cooling-down stops. I've never adjusted carburetors before and the youtube videos I've looked up have only left me more confused. Does anyone know of a youtube (or elsewhere) video showing how I diagnose/adjust/fix the early 60's 1-barrel Holley carburetor? My original Ranchero (back in the 80's) could put the choke back to wide open after only a few minutes of warm up, but this engine immediately dies if I do that, and requires me to keep a partial choke just to keep running, which also makes it run at higher RPMs (not a comfortable idle.) I'm assuming that means it is running too lean, if I have to keep it somewhat choked just to keep it from dying. Is that a correct assumption? I should mention as background, I did put all new tune up parts on: plugs, wires, cap, rotor, points, condenser. But it runs exactly the same as it did before I replaced all those things, zero change... Grateful for your any input and instruction, as always!
