What, exactly, is the purpose of this step? Rotating the crank 360 degrees
will put it exactly where it was. If you want to check the distributor
position
to see if the rotor is about where it should be when #1 is at TDC ready to
fire just turn the crank until the valves for #4 are "on the rock"
instead of
the number 1 cylinder.
In the four cycle suck, squeeze, bang and blow process TDC in a cylinder
occurs between squeeze and bang, and again between blow and suck. The
blow /suck TDC is when the valves for that cylinder are on the rock, given
a basic, symmetrical cam grind.
The length of the bolt or nut whatever you firmly attach doesn't matter,
though the shorter the better to prevent deflection. Wherever the two
marks for the clockwise and counterclockwise rotations end up, TDC is
halfway between the two.

email, Team.Net admin stuff, etc. to catch up on.
