Sorry, can anyone explain? What should I do? Running is correct, idle floats... If its is about 1200 RP the idle goes down up to 900-1000... If > 1400 - slowly falls after the throttle... It annoys me. Good drop, but bad idle http://www.youtube.com/watch?v=RinLZBI_KB8&feature=youtu.be Slow idle down http://www.youtube.com/watch?v=2teUpD86TjM&feature=youtu.be No leaks in air supply, new sparks, synchro, new fuel... Lean mixture?
