ok im starting to get confused again. at first i wasn't geting any spark on left side of engine as your looking at in from behind. i got a new coil put it on and it did not fix tha problem. then i noticed one side had the kill switch terminal down and one side up. i turned the new coil to match the one on the engine, that would be down. i know have spark on both sides. but know i noticed i have two #2 coils. motor runs fine but when i turn key off motor keeps running. i even ran a wire to one of the kill terminals on the coil and touched it to gound still ran. in some of the documentation u sent me i found a section that said kill switch terminals should b pointing out or up. when i switched them now i have no spark on either side. now so u
