evo.46surg

[lowpass]

:confused:my evo .46 has some interesting things happening while running in the air. when the tank is about half empty the motor surges. but not every time. ive changed the fuel lines and the carb gaskets and put foam around the fuel tank to reduce viberation. still the problem pops up from time to time. any idea's?

Are you using muffler pressure?

Does the surge continue from half tank to the end of the flight?

Are you flying a trainer or a sport aerobatic type of airplane?
