QuestionI have a 12 yr old Honda mower (90cc, OHV, about 5.5 or 6 HP). It ran fine for years, then last Spring would not start. It acts like it is not getting a spark to the plug. I'm thinking it's the magneto. Is there a way to tell for sure without buying a new mag? I don't want to put a lot of money in repairs for a mower this old, but I would replace the mag if I was pretty sure that was the problem.
AnswerDoug, you have to use a "spark tester" or with a insulated pliers, hold the spark plug wire approx 3/8" away from ground (spark plug out !!!!) and have someone pull on the rewind.You should see a spark jump the gap. If not, the coil needs reolacement, Best of luck,,,,,bob
