Hi everyone,
First a disclaimer or two.
The entire engine isn't see through, only the head.
It isn't a steam engine.
Then why post it? Seeing how the flame spreads in a cylinder is pretty neat. Seeing how different fuels burn is pretty neat. Seeing what things increase power is pretty neat. The brake he built to measure power is pretty neat. The fact that by the time he got done he had a turbocharged, electronic fuel injected B&S engine is pretty neat.
More of the series in the next post.
Later,
Jerry Christiansen
