I've let cold weather, holidays and general discouragement move the TD to
the back of the garage where it gets an occasional scowl as I walk by.
Readers may recall my recent odyssey into relplacing noisy tappets and
pushrods, which was followed (though maybe preceeded also) by intermittent
bad performance. It always starts, but will run rough, and seems to
alternate between three and four cylinders firing under acceleration.
Since last posting we had isolated the ignition system, with widly varying
resistance among the spark plug wires.
I replaced them, the rotor and the distributor cap, and reset the valves to
.013 cold. Test drive was disappointing, with moments of restored
greatness, but mostly hesitation and mild sputtering. Lucas Sport coil,
Pertronix ignition and new plugs compete the ignition system, so it must be
somewhere else.
Carbs performed normally in Colortune testing. Could I have gotten a bad
tank of gas (water contamination or worse?) I've got a fuel filter in the
system, which is clear. I'm getting desperate enough to start trying fuel
additives.
