Default carb problems

little oil an needle and seat rubber o ring to seal it. check cams and make sure they are not working the accellerator pumps at idle. this can happen. .015 lash on accelerator pump limkage is at full throttle, not i nthe idle position. this is to insure the rubber diaprham doesnt bottom out at full throttle do vacum test in gear, at idle. and if over 10 inches or more,use a 6.5 power valve. if lower than 10 inches use 1 size smaller then the vacum reading (eg. 6 inches vacum, use a 5 power valve. use one too low and it wont open up. this is the way i do my carbs and they all work art
