Since my TM specifically calls for the motor to be running and the use of the special tool I don't think that's its any more or less accurate than stopping the motor. Feel free to check my 235 when you see it and if its off, I'll buy you a warm diet soda.
What is funny is that people think that valve adjustment is some sort of microscopic adjustment done to the outer electron shell of the molecules making up the steel valve stem.
Adjusting the motor cold and counting nut flats is just as good as a feeler gauge. Or even better... if it taps to loud its to lose, if it backfires its to tight.
Its a lash setting.... think along the lines of horseshoes and hand grenades.
