I ride a Piaggio scooter with a single cylinder engine. Recently I broke down and the engine wouldn't restart. It turned out the spark plug was stuffed. How can I ensure that doesn't happen again?
What is the difference (besides price) between normal, platinum, and iridium spark plugs?
When dealing with a car with aluminum head(s), what is the proper way to extract a broken sparkplug?
Where are the coilpacks located in a 1998 Buick LeSabre? Images would be most appreciated. Robert
