You contradict yourself, John;
You state that you also use an indicator in the plug hole...... What
you and others say are great for an engine on the stand, but not for an
installed engine.
The straw in the plug hole works very well for an INSTALLED engine,
since it's near impossible to put on a degree wheel in a car that's
operable. The straw will get him in the ballpark and will tell him what
the marks on his pulley are. That was the original question.

That doesn't work because there are several degrees of crankshaft
travel when the piston is at the top of it's travel with no visible
movement of the piston, the method David described is very accurate and
the method we used to find TDC in Radial airplane engines using a
degree wheel and an indicator in the spark plug hole.
