Thanks for the help guys, what Flyinrazorback said is exactly what is happening, I start it up and it will transistion the first 20 seconds in the pits but as soon as I get on the runway it starts acting up ,,, I guess by the time it gets out to the runway about 30-40 seconds from start up it is doing exactly flyingrazorback said, I am going flying today and see if it fixs it,,, and for FYI I already have the Carbon Fiber Carb plate on the Carb,,,,,
