I am just sitting here thinking (very dangerous thing to be doing) about why advancing the timing makes more power. If you go from 4,6,8 degrees before TDC to 10,12,14 degrees on the timing, why this makes more power. This means that you fire the plug 10+ before the piston reaches TDC. The piston is still moving up when you decide to fire the plug early. When you fire the plug  early by advancing the timing, the piston is still trying to move upwards, but you have fired the plug and the force should then try to move the piston down, but the piston must still pass TDC before it can be forced down.  Why is that?. I am confused. I know that advancing the timing makes more power, but WHY. Your firing early
Just wondering
