Thanks Steve for explaining it. That is ingenious and practical.

It is a Tee with a top branch made of clear tubing. The side of the Tee is connected to the spark plug location. Using some fuel line (anything handy will do), I connected this side branch to an old spark plug with the internals removed. An o-ring seal was used on the spark plug instead of the metal one so hand tightening was enough. The bottom of the Tee is connected to a balloon with soapy water in it. Squeezing the balloon and releasing it will leave a soap film across the side branch. Turning the eccentric shaft will displace the soap film up or down the top branch of the Tee. It will take a little trial and error to get close to TDC where the soap film isn’t blown completely out of the top branch.
