Rhiannon is correct. The setting and rising points of the sun will travel south after the autumn equinox, slow down and hit their southern limit at the winter solstice and then come back north once again, through the spring equinox position, eventually to the opposite limit at the summer solstice.
The rising sun will head south every day, reach its mid point and curve back north to set on the opposite horizon to the west. A 'c shape' would be a good way to describe it.
A great route to baking your brain with this stuff is Clive Ruggle's 'Astronomy in Prehistoric Britain and Ireland' or Douglas Heggie's 'Megalithic Science'. If you really want to hurt try Thom's 'Megalithic sites in Britain'.

Basically for the sun to shine straigh into the larger of the two chambers it would need to rise further north-east. From the pics I have up it is roughly at due east. Does anyone think it would be possible to rise that far north? The rising sun will head south every day, reach its mid point and curve back north to set on the opposite horizon to the west.
