Can anyone outline the procedure for timing a 1962 DU-10S V-4 ? Has a dual-point, automotive style distributor, cogged timing belt and #1 is clearly marked on the distributor cap. #1 cylinder is front /top right when viewed from back. The firing order is evident as each spark plug wire is marked....1,2,3,4. How many degrees advance at TDC? I can't find any marks or anything on the flywheel or inside the distributor to indicate when the rotor is exactly at #1 electrode.
