Gnome Monosoupape 100 Rotary Engine

AirVenture must have 500 engines on display... real ones, mockups, and a few which are pure fantasy. Most are the same old thing in a different color.  However, here is one you do NOT see every day, a Gnome Monosoupape 100 rotary.

That's a rotary, not a radial; The crankshaft is fixed to the airframe, while the crankcase and cylinders whirl around with the propeller. Not cheap, but perfect for your trusty Sopwith, or with an Oberursel data plate, an early Fokker. They're available brand new from Classic Aero Machining Services of New Zealand.  For more information, visit

Priming (with) the Pump!

There is a never ending debate, with good arguments on both sides, about priming the simple four-cylinder, carbureted Lycoming engine before starting. For as long as we can remember, certified aircraft have had the good old priming pump, where you pull back slowly to fill the chamber with fuel, then push it in to squirt that fuel into one or more cylinder's intake chamber. This works, so long as there are no leaks in the system, the copper plumbing hasn't broken, and there are no blockages in the nozzles. It often gets the engine started as well!
