Tuesday Torque: Oil City Two-Stroke Hybrid Engine

The lower end of this Oil City engine is just like a steam engine, and many early gas engine in the oilfield began as steamers, then were switched to run on gas by changing out the top end.  I suspect that for a while at least, you could order engines either way from some of the oilfield related companies.  This two-stroker runs about like the two-stroke Bessmers, and I really like seeing hot-tube ignition in use.
