[TR] Shade tree Timing

[Dave Connitt]

Bill,
Did you measure the diameter of your crankshaft pulley? I have a new stock 
one down in the garage. I will measure it tomorrow and let you know what I 
come up with. I imagine all the stock pulleys are the same diameter.  I 
thought it was pretty interesting how the punched hole in the pulley was off 
so much from actual TDC. Of course that assumes that the gentleman's 
technique was that accurate..
I will let you know tomorrow on the diameter and what each degree works out 
to but it sounds like you are pretty close.
