For anyone trying to time a centrifugally advanced B Distributor on an A engine, and using the conventional method of timing by inserting the front timing pin in the recess in the timing gear, first:
1. Do you know if your timing cover is a Model A timing cover which was designed for use with a manual advanced A distributor? or,
2. Do you know if your timing cover is a different, Model B timing cover which was designed for use with a centrifugal advanced B distributor?
3. What type of head is on one's A engine?
Once one's timing cover is identified as either an A timing cover or a B timing cover, (e.g., differences are indicated Mr. Vince Falter's "Model A Ford Garage"), one can continue to become informed on how to time one's engine using one's timing pin.
