      I have a engine stumble or bump when I retard the throttle from cruise and this continues all the way to landing,seems to be from 2000 and below RPM.
      I have installed new intake gaskets,hoses,and clamps,cleaned plugs,new o rings on primer,checked timing!! Still have the stumble and the carb was overhauled by Avstar 4 years ago if that is relivant.
      Anyone have or had this problem?
