A typical core engine as found in barns, shops, hangars, warehouses, and hanging on abandoned aircraft. This
one is an A65 and was sold in “as is–where is” condition from an abandoned freight liquidator for $250. Dented
oil sump is very common but can be corrected by pressurizing the sump with compressed air and gently heating the
dented area with a torch until the dent is blown out.
converted to C90s, but the cost can be dear: The
crankshaft, connecting rods, cam, lifters, pistons,
rings, carb, and valve springs must be changed along
with many other hardware items and operating
adjustments. Starters and generators are typically
fitted to the engines, making the C90 a strong, versatile powerplant for many light aircraft.
O-200: ENGINE FOR THE FLYING PUBLIC
There is one more page to the story, a page that
closes one chapter in the proud history of the four-cylinder Continental engine and begins yet another:
the O-200. With the burgeoning demand for large
numbers of lightweight, affordable, reliable aircraft
engines in the 1960s and following, Continental
refined its classic engine into another standout in
aviation history…the O-200. Together with the
Cessna 150, the O-200 would go on to become one
of the most-produced flying machines of all time,
deserving a story of its own.
