I have a TR 250 and am having difficult setting the slow running. Choke off, slow running screw retracted but engine running at 1500 rpm. With air filter off I can observe that the valves are lifting by about 1 mm. Once the engine is off these drop down freely to close. I have disconnected the servo and blanked it off but no change. These stromberg 175 CD2 carbs appear quite complex. I am thinking there must be air leaking somewhere. Any suggestion as to what might be the cause and how do I correct itÂ
