With my basic mechanical knowledge I cannot make sense of it....any body care to enlighten me?

The engine is effectively a pump, when the throttle is closed and the choke is off the inlet is closed and very little air gets in so the starter can turn it over fairly easily. When the throttle is opened or the choke turned on (which opens an auxiliary air passage, more air is allowed in which has to be compressed to pump it through the engine. This extra work would appear to be beyond the capabilities of your worn out battery.
