im almost done with a full rebuild of my 240sx and i realized that when i removed the distributer, i did not mark its position clearly enough. so i do not know what it was set to beforehand. i know that i need to have the #1 cyl at TDC, but i dont know how i should set the distrib. before start up. Furthermore i dont know where the rotor inside the cap should be. should it also be set to the #1 cyl spark plug contact point?
