I won't consider it unfortunately, though I heard about glow engines change their behavior while being installed inverted. It's not glow's thread so I'd stop talking about glow motor
Does this principle go installing the engine inverted with front end carb and rear end carb too? How about NGH engines which have front end carbs? I've seen a lots of videos installing the engine upwards direction. That's for sure gas engines direction won't matter engine's behavior either direction it's installed?
