Why engine sounds 'wrong' when rotated backwards a few degrees
mx_rob posted this on TT about the motor sounding 'wrong' when rotated backwards a few degrees to get right on TDC.
"Why you think you are screwed when that happens is the starter sprague clutch (bearing) is engaged as soon as you try to rotate the engine backwards. It takes a bit of effort to roll it backwards since you are having to spin the starter motor through all of the gearing reduction... and since you are turning the crank the reduction is backwards so the starter motor has to spin a lot of turns for a small amount of crank movement."
