The Continental IO-346 engine is a fuel-injected four-cylinder aircraft engine that was developed especially for the Beechcraft Musketeer Custom III by Continental Motors. It was produced for that aircraft between 1965 and 1969.
The Armstrong Siddeley Ounce was a small two-cylinder aero engine developed by Armstrong Siddeley in 1920. The engine was originally conceived as a test piece but ran very well and was put into production for early ultralight aircraft and use in target drones. The Ounce used two cylinders from the preceding Jaguar I radial engine.
