To be honest it doesn't matter if it runs because I will never start it. Reason being I am not much of a racer, one reason is because the nearest track it 200 miles away. However I love building R/C cars (I own 13) and I thought I would use the engine as project for my maching major project.

So from there I thought a Brass engine would look good or a possibility of using lucite or a clear plastic.
