Does any one happen to know what the measurement is between the centre of the piston at TDC and top surface of the bottom side of the head, where the spark plug is located is ? I would go and measure it, but i can't at the min..... and I need the measurement! For the avoidance of doubt, Its not the squish - its the distance between the piston crown the bottom of the plug 'ole! Thanks in advance if anyone happens to know!
