RARE 1921 Briggs and Stratton Model F (Full Power) - Tear Down and Revival!

Well I recently picked up a deal of 100 lifetimes and was able to acquire some really early and rare Briggs and Stratton Engines! Figured I'd start with the biggest gem of the lot- The 1921 Briggs and Stratton Model F! This is an engine I have been wanting since I started collecting engines but never one I thought I would ever be able to own! I am super grateful to be able to own such a fine, running example after only a few years of collecting! Hope you all enjoy seeing the tear down and revival process on this awesome piece of history!
