Hey guys, I'm using a 4 Stroke Magnum .56 XL ringed engine. What prop should I use?? Also, how did you guys work around the Fuel tank being higher than the Carb? The carb on the engine sits right in the middle of the two fuel lines on the fuel tank. I had a .61 Evolution engine in it and the carb was wayyy low so it wouldn't start at all. All it did was got flooded. I hope it doesnt do the same to this new engine I got.
