I recently bought a 1989 Suzuki Fa50. It fired on the first kick and ran great when I tested it. It was laid down on its side in the trunk for about an hour on the way home. Now it won’t fire at all. It’s sparking and sounds like it’s very close to firing. I’ve tried all the tricks I can think of from letting the spark plug air out in case it was flooded, checking the air filter, cleaning the carb. Nothing has gotten it to turn over. Any and all suggestions greatly appreciated!
