hardtimes,
The flywheels should arrive near the end of April 2021.
Benson,
The "Builders Guide" that comes with the engine kit is abbreviated and has been revised several times. The latest revision of the "Builders Guide", "Doubling the Flow Area of a Model A Oil Pump", and "Installing an Oil Filter" can be found at
www.modelaengine.com
Click on "Guides" and then click on the guide that you want to read.
When you open one of the guides, the date under the title is when it was last revised.
