70s model 3.5 Briggs and Stratton cool bore sump removal and valves prepared with scotch brite

This is a testament to the long lasting longevity of theses amazing older engines. The quality can so evidently be seen in comparison to the modern trash Briggs and Stratton makes today.

Hey Kevin very interested about the engine stand you're using in this video. Could you please post a video on it?
Thanks, George Ireland
