hey I have bought a venus 40 from great planes and it calls for the engine to be mounted inverted. I'am wounder how my os is going to run. I heard that mounting a motor upside down causes the motor to flood and die. I'am woundering if anyone as tryied to mount a os 46ax inverted if they had to use a on board glow heater, or a longer glowplug or the the stock setup did fine or what?

any comments would be appriecated thanks
