A friend of mine was having bad problems with his 110, it would shake violently, tried everything, so BME sent him a different type of carb to try, installed it, motor ran fine on the ground on the rich side, took off, and immediately completely leaned out and seized the motor, sent back to BME, and they dont want to stand behind it. I dont understand it. My 110 ran flawlessly. It is very easy to see why everyone flys DA.
