I am a new owner of a 78 inidan moped. It only has 1500 original miles and had been running great. I was riding last night and the engine stopped while riding it. After looking at potential problems I noticed the spark plug had corroded and no longer seemed to be working. Question is would this cause the engine to stop running after it was started and how would you advise fixing the connection cable to the spark plug which corroded off? Any help would be great appreciated.
