pulled the plugs on my new to me 75 1.8 with carbs today. 1,2,&4 look good grey in the center (3 electrode plugs) black around the sides. # 3 was totally black. it was idling rough so I pulled one plug wire at a time to see the difference it made. All but #3 made a difference. When I pulled #3 there was no difference at all. It has an electronic fired dizzy in it as well. Cap and rotor are new. What ya think?
