Tuesday Torque: Two Nice IHC Engines

Here are a couple of nice engines that look pretty similar. Engine aficionados will note that the one with the new paint fob is a hit and miss model, and is the older engine.  It has a thermosyphon cooling tank, which was soon phased out to a tray cooling system, and later, to a screen cooler over a tank.  The thermosyphon used a lot more water asn was heavier to move around.  The newer, original finish engine is throttle governed.
