Well I finally got around to firing the ol'e engine up after I relocated the fuel tank up higher, which now is slightly higher than the carb. When before the tank was lying on the bottom of the fuselage causing the engine to bog , and lay down and so fourth, but when I fired it up today it ran like a Swiss watch! No bogging, no hesitation, it just ran perfect and sounds really good! I'm happy with it and glad I bought it.
