You go right ahead and do it that way if you want, but in the words of Jerry Clower..... "I ain't gonna do it!".
big difference between torque (twisting) and pulling (pressure). If we crank the engine without supplying fuel or ignition (so there's no combustion), the compression stroke of the piston produces a modest pressure peak (perhaps 120 PSI) right at TDC. On the other hand, if we provide a combustible fuel/air mixture combustion causes the pressure to build to a much higher value - typically 800 PSI in a normally-aspirated engine. Just sayin. Oh, by the way thanks for the discussion, I appreciate your view and you know your stuff.
