To time the ignition, turn the engine with plugs removed (its easier) and turn engine with your finger over number ONE plug hole when you feel compression on your finger stop. Go to the timing hole below the starter and look for the timing marks on the Flywheel. turn the engine until the marks appear and you look for the 7 degrees mark (count the lines on the flywheel) use the ones that appear first in the hole. Line up the 7 degree mark with the mark on the Engine mounting plate, You need to turn the engine slowly until the marks JUST line up, you can't turn the engine back-wards if you go too far, if this happens you will need to turn the engine over two revolutions before you get back to the same point. When the marks are lined up, now slacken the distributor and turn it so the Points are JUST at the point of opening (not open) and re-tighten the Distributor Clamp. That is the ignition set, check the Rotor that it isn't cracked or damaged in any way, same with the distributor Cap, any marks or cracks, replace it as the HT can creep along the marks. Then check the terminal that runs through the side of the Distributor Bowl that the insulator hasn't worn through with vibration. Change the Condenser if you haven't already done this as these can fail anytime and always change them if the points develop a spike or a hole in the contact faces as it is starting to fail. If you would like this in a bit more detail, email me and I will send it....John(UK)
