Stupid Distributor Questions

Does the car run hot? If not you may be able to run a colder plug. You should start to show some color on your plugs if you`ve run it some now. If they`re too clean you may be running too lean or too hot of a plug. I`m running either 63`s or N9Y Champions in my car and they are a nice chocolate brown. You`ll be okay with the MP electronic ignition as it is from the box. Although there`s always room to dial it in, just installing the electronic will be a great improvement over your single point. Are the idle mixture screws on your carburetor leaded over? If so, they may be set too lean. I do think the throttle plate is not covering the venturi at idle therefore drawing vacuum from the run circuit and increasing idle speed. You may have to back off the idle speed adjustment ,advance the timing, and richen your fuel/air mixture. With that you should be able to position the throttle plate over the vacuum advance orifice. Let us know what you do George.
