Stupid Distributor Questions
You`ll have to carefully drill out the lead. A left hand drill would be the best thing if you can get one. That way if you turn the screw it won`t bottom out in it`s bore ,rather back out. If a right hand bit is all you have just be very careful when you get through the lead and contact the screw heads. Once you get the bulk of the lead out you can dig out the little in the slot of each screw and back out the screws. Here`s a photo of the carb inverted, you can see the slot on the left (the one that should be covered at idle) that leads to the vacuum advance port. You can also see one of the the round holes that contain the idle mixture screws. The ends of the screws may be protruding into the throttle bores on your carb. HTH.
