You need to turn the idle jets in and count the amount of turns till it is all the way in. Then remove the idle richness screws with the tabs on them. There will be a small rubber ring and a smal metal washer, the rubber ring goes in first and then put in the metal washer( make a note to be careful of these). Need to work carb spray back and forth between where the idle richness screw goes and the non-removable pilot jet, next to the main jet. Once passage is cleared, turn the idle richness screws in all the way then back them up the amount of turns you counted before. Any more questions, e-mail me at irishdaddy1977@aol.com
