Frank, I counted 83 teeth on my 70 Chrysler 35 HP related to your timing method that I like. Will the number very even though I read Chrysler 35-55 HP are basically the same except for pistons? How many teeth did your flywheel have? I used a Computer Aided drawing program (CAD) to make a 360 degree protractor to print and use on card stock. Then, I remembered the flywheel and teeth are a protractor and KISS! ?Keep It Simple Sir?. Thanks for your experience and sharing.

Re: 72 Chrysler 55 Hp, Timing
The reason for the tool is because the crank can move a degree or two at TDC without moving the piston, so the piston is measured at 28 degrees (36 0n the bigger engines). Since you don't have marks on the flywheel, it is moot unless you are setting the points with the flywheel off and use the piston to determine closing of the points.
If you can make the tool, fine! If you can find an Intertech manual it gives the actual measurement while most others dont.
However, If you work accurately, you can feel TDC through the top plug hole and then mark the flywheel gear and the block for 0 degrees. You will not be off by more than a degree. NOW: you count the gear teeth and divide 360 by that number. This gives the number of degrees in a tooth spacing (If I remember correctly it is 4.5) thus you can use the teeth to determine the timing setting you want. --6 teeth to the right of 0 will give 27 and 7 will give 31.5 advance. That's how I do it on my 1967 55.
