This sounds right to me. Everything is mechanical for timing so something;
either the timing chain or the distributor is jumping teeth. If it was the
timing chain you wouldn't get it back with moving wires since the cam would
be out and all kinds of things would be happening with the valves and such.
I seem to recall, but not enough to say exactly, that when certain cams are
put in you have to make sure you have a certain gear on your distributor.
And I am talking metal types here so that the distributor gear will go
before the cam gear. Likely, as stated, the gear on the distributor
(hopefully versus the cam gear) is bad and you are jumping teeth. It would
make sense that this would happen under the stress of startup. Same for a
timing chain. I would pull the distributor and see what the gear looks like,
and if OK and tight, then see if you can tell the status of the cam gear by
peering down the hole.

The distributor is gear driven. If it it is jumping so bad you have to move
wires, it must be jumping teeth. It is crucial that the distributor gear
matches your cam.. cast iron vs. steel I think it is. I would pull the
distributor and check the gear. If its worn like I would suspect, you might
have damaged the cam as well.
Or it might be possible your dist is not seated all the way down somehow??

Subject: [Tigers] Timing deviates - advice needed
I put out a list MayDay a year ago when suddenly, upon starting, the car ran
absolutely brutal. Undriveable. Adjusted the timing, replaced the fuel pump
& fuel filter, drained the fuel. Nada. Barely running. (Tony, and others,
thanks for the input). Then I finally get a guy I know (not a mechanic, but
good problem solver and mechanically knowledgeable) to look at it. Car
starts and runs not too bad (no changes made), he moves the distributor, and
voila, runs perfectly. Start it a few times, drive it around, set the dwell,
all's well.
Some time later I get a bad result again, and my mechanic buddy moves the
dist to full lock, and it's running 90%. We move the dist wires one position
so we can move the dist, then set the timing correctly.
He checks everything: float bowls, condenser changed, dwell set (got some
strange readings tho). Runs awesome.
Some time later I get a bad result. I check the timing and I'm at zero
degrees. I move the wires one position in the opposite direction, adjust to
16 degrees and voila!
Some time later...well, you get the picture.
Something seems to throw my timing out substantially. If I make adjustment,
my timing goes out the other direction.
This does not occur while I'm driving. Only upon a subsequent start-up.
Someone highly regarded thought timing chain, but I checked (observing
degrees of movement when manually reversing crank direction) and it would
appear to be well within spec.
New coil, points, wires 1000 miles ago.
I'm running a Mallory dual point. I want to keep it (not the LAT Ford dual
point, but historically similar).
It doesn't appear to be worn, the points are clean, rotor is good. Swapped
out condenser.
Cannot seem to source new points (though they are shiny, not burnt).
Tried to start it in the fall to go park it for the winter, and it would not
even fire; suspect the timing might be way out this time. I verified there
is spark and fuel. Covered it up for the winter.
Mallory won't help. Completely unsupported and no parts avail.
Couldn't find a shop that'll just take in the distributor and bench test it.
Any ideas? Would prefer a remedy to existing.
Should I take the leap to electronic? If so, what would you recommend?
Spring is coming, and I've got to have a more trouble free summer this year.
All suggestions appreciated.
I will queue up your thoughts and likely be able to get after it when Spring
shows up in 3 weeks.
Appreciated! Please solve the riddle!
