Spring is here....and I have no spark on the qt50. There is compression and gas is flowing. It ran last week although not flawlessly. There were major misfire issues and problems ideling without throttle attention. Since it rolled out of my dads barn my buddy and I did minor upgrades like throttle and choke cables, fuel filter, carb cleaner, new hoses, battery, bulbs. Last week when It was running obviously there was spark, but still needed 30 cranks to get some life out of it. Seems like the next reasonable step would be to get a ignition coil. Any opinions and advice on my logic and reccommendations on aftermarket parts as I don't see anything original that would make sense?
