tony283 Posted April 21, 2011 Report Share Posted April 21, 2011 (edited) The needle drops into the main jet and the pilot jet is located in front of the main jet. Blow compressed air through from below. Tony Edited April 21, 2011 by tony283 Quote Link to comment Share on other sites More sharing options...
