John, I used a hybrid of all the methods I thought made sense. The paint brush handle I used for painting on Curil T was my dowel. I turned the impeller clockwise until I felt TDC. If I passed TDC I went around again twice. I wiggled the rockers and confirmed that they were the most lose when the dowel (paint brush handle) was at it's highest. This and the notch in the flywheel helped my final8ze my TDC mark. I experemented many times before coming to this final approach.

For those who attempt this method: ensure your dowel is long enough to not fall in the spark plug hole as John mentioned and make sure you guide the dowel so the piston does not catch it and break off inside.
