Default Mounting an engine inverted.

Some four stroke engines will benefit by using an on board glow driver when mounted inverted, also make sure that the spray bar on the carburetor is not below the pick up of the tank (if the plane is designed for an inverted engine this should not be a problem).

Make sure that you do not flood the engine when starting, if using an electric starter a flooded engine will cause damage to the engine (bent or broken connecting rod).

I have run my OS.91 Surpass inverted with out a glow driver and have not had any problems with loading up or flooding.
