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

I have 2 46ax's mounted inverted. Just check you low end needle valve adjustment when you run it the first time so it's not too rich. Other than that they are great inverted.

Thanks for the info. I will try it and see how it works for me.Kevin

You won't have any problems running the AX inverted as long as you try to get the tank centerline as close to level with the carb as possible. If the tank is too high you will have problems with the engine flooding.
