Hmm,rocking it back and forward then it started?
Sounds a lot like hydraulic lock,thats what you get when the cylinder head gasket is gone.
Take out the spark plugs and spin it over,then refit them and retry.
If still no difference use one of the jump leads to connect the battery negative to the engine,this will bypass the engine earth lead.
