Whoever is fixing your mag better not screw up the rotor time. [Reply]  [No Email]

Rotate engine to top dead center on compression stroke #1 cylinder. 2. There is a small view hole in the bottom of the bell housing. You should see "d/c 1/4". This wording can be difficult to see and it is small. 3. If you succeeded in step 2, turn the mag so that your rotor points to # 1 and bolt it up properly lining up the key way. That's it. Any other method could yield problems. [Reply]  [No Email]

It will already be back where it was at the start. An alternative to using the old gasket as a guide, you could put witness marks across the magneto flange to the block before step 3.

THEN DON'T MOVE THE ENGINE WHILE THE MAG IS OFF. When you are ready to install the mag you rotate the rotor to the spot shown in your sketch and install the mag. You can use this procedure with your car or truck doesn't make any difference if it has 6 or 8 cylinders. Just don't move the engine and make a sketch that includes distributors too. I did that on my 1981 Mercury Cougar when I needed to replace the thermostat. The engine started right up I did have to connect the timing light to set the timing. Hal [Reply]  [No Email]
