RE: Ignition timing
Here's one I made how I like them to be graduated. If you can't enlarge and print this one, let me know and I will e-mail you one. And by the way, you can't really find true TDC with a dial indicator without measuring to a certain value on each side of TDC and then splitting the difference, as mentioned above. The positive stop method is easier, and faster...
