Here's a smattering of questions about my F ('71) state of tune, the stock ignition, and an alternator question:
1. The engine runs great for an old 6-cyl, carb was re-built by Jim C. several years ago, I just replaced the exhaust manifold with new gaskets all around, plugs, points, wires, timing, are all tip-top. Smog removed, non-US vac advance dizzy. Vac gauge reads strong 21 in vac at idle. When hot, the engine idles pretty rough, not like it's missing on any cylinders(like idling on 5, I know what that feels/sounds like), just a general roughness. the vac guage still pulls high vac, but the needle wavers slightly, maybe 1 in vac back/forth.
Q: Could this roughness be the weak stock ignition at idle, or maybe valves out of adjustment?
2. Just completed the PIA crank pulley swap for a 3-row pulley, for my upcoming PS conversion. Replaced the WP while I was at it with a 2F pump. Now, however, the alt does not align well with the WP/crank pulleys(WP and crank pulleys are perfectly inline with each other), and I am getting BAD growling noises from SOMEWHERE down there when idling. Sounds like a diesel. Much belt squealing also.
Q: Could this belt mis-alignment with the alt cause it to make bad (bearing?) noises? If I remove the belt to try to isolate the alt (see if the noise goes away), will the truck start/run on just the battery for a while?
