Kevin,
No, you have to make sure that the rotor points to no.6 (front)
before setting things. Actually, I don’t guess in matters whether
you set the static timing for no.6 or no. 1, so you don’t really
have to worry about it…
Also, there is a small chance that the flywheel was last installed
180 degrees out of phase, in which case there won’t be a mark there
at TDC 6, instead there won’t be any cylinders at TDC when the mark
shows up. But if it’s correct, it’s very useful. If it’s not you
have to verify TDC with a dial indicator down into the spark plug
hole. If you don’t know the car’s history this is a good thing to
do once (set the sump-bottom pointer exactly).
4.2s don’t have this nice feature, I always wondered why. If you
have a timing light with a degree offset knob you can time the car
from the top of the engine which is a BIG advantage!
Be sure to lube the distributor before doing this, and then every
2500 miles. Check with your hand that the rotor moves a
significant amount against the advance springs without any drag,
and returns under its own spring pressure completely back to the
end of its travel, i.e. it won’t move more when you push it (the
rotor may move on the shaft, but the shaft should not move) If
not, put a drop of liquid wrench under the rotor and work it back
and forth a lot, then more, again and again until it moves
completely freely. If it does not free up, you need to disassemble
the distributor and clean up this rotation corrosion. Otherwise
you are not getting the advance the car needs. And this is a
pretty commmon problem…

The original message included these comments:
Will the mark on the flywheel and the pointer on the balancer
ensure that I am not 180 degrees out with the distributor?
