You gave away at least On= e.  I used it to find TDC on my 13B that Sunday afternoon when I got h= ome from Paducah, worked great, and confirmed that the timing mark on the c= ase was in line with the mark on the E shaft.

The attached photo shows a device that makes it ea= sy to determine the location of the minimum combustion chamber volume (TDC)= within a degree independently of any existing front pulley or flywheel mar= kings.  Connect it to a spark plug location and just rotate the eccent= ric shaft to the point where the soap bubble in the clear tube is the highe= st.  It might be worth a try.  I made up a number of these to giv= e away at the Paducha fly in last summer.  The lack of interest was su= rprising since I couldn=E2=80=99t even give them away.
