This is similar to how I adjust my valves. I run the engine hot and check things, and record the findings for each valve. Then I shut things off and make the adjustments carefully with the motor off, and restart and measure again. The technique below adjusts valves as the motor is running, and I've found that to be somewhat difficult and prefer my own hybrid method as noted in a previous post on this thread. I offer this "for your information".
