Default Re: OT: 1935 Richardo and a two stoke Spitfire engine

We can thank Sir Harry Recardo for the Model A head design. Although the flat head is not as efficient in pumping air as the overhead design, the combustion chamber design is highly efficient in burning the fuel. Recardo did pioneering work in combustion chamber design in the 1920's leading to the Model A head design.

Driving's a blast, a blast from the past.
