PhoenixDX Posted September 2, 2008 Report Share Posted September 2, 2008 Have ya done the Timing with a timing light. As my 4k use to do what your describing. :jamie: If timing doesnt work, losen off the 12mm bolt holding your Dizzy in place and slowly turning it clockwise or anti- clockwise till you hear the motor running smoothly, be paitient coz the difference of a degree can change the idle. when the engine starts running true, then then you shouldnt have a problem with surging. Another thing that could be doing it could be your Mixture is to rich/ lean. have a play is your best bet. :P Quote Link to comment Share on other sites More sharing options...
