I guess every once in a while there's a flawed part that makes it out the door. This time I got the part that escaped notice. The mechanism itself isn't straight and tight and won't do what it's meant to do because of that. Luckily I bought a second one from Sudco that I compared to this one and realized why I wasn't getting any spark from the plug. I can use it if I bend the piece and pinch the point holders down where they need to be. But I shouldn't have to repair a new par o bought to repair the bike. Sorry for the negative review but the one I got shouldn't ever have passed inspection
