More likely it will fire during the compression stage and cause a violent backlash. I don't think an engine firing during the intake stage at cranking speed could possibly produce enough force to get through another cycle and actually start.If the timing key in the flywheel is sheared and the spark is arriving while the inlet valve is still open then you will get a backfire through the carb and then generally the mower will stop as this cause it to starve itself.
Mechanical energy is proportional to the square of speed. Voltage is proportional to the speed. Double the speed and you double the voltage, which roughly quadruples the energy /per spark/, but you also double the number of sparks. 8x the power. Except in the so-called "Southern Hemisphere" which I doubt even exists.The MECHANICAL energy is of course proportional to the SPEED that the flywheel is moving
Couldn't tell you how many times I grabbed a coil wire or plug wire to check for voltage. This has NOTHING to do with memory loss... just saying I don't remember.Stand on something that is wooden and do not touch the mower anywhere else or you might very well also confirm a spark will follow the path of least resistance ( ouch )
