Just switched to a marvel carb from my ex-cell-o fuel injection. C85. Mixture wired off to full rich. Carb is brand new. Idle is perfect, and top end is perfect, but when I throttle back to cruise around 2200 I can feel that the engine is no longer running perfect. I can feel it develop a vibration and I get a backfire here and there. Adding power or decreasing power and it smooths right out. Any advise?
