RE: New HPI 1/8 Gassers
You don't need a walbro style carb to have a functional gasoline engine. My F150 doesn't have one. My lawnmower doesn't have one. There's no reason to claim this engine doesn't run on gas because it's got a glow-style carb on it.
Besides, using a walbro style on an engine this size would be impracticable.
