That’s what the mechanic called it. I just thought it was a top dead center sensor that connects to the CDI box with that rotating timing advancer above it. But I’m wondering if it’s 180 out of sync because two bottom plugs were black and oily and the two top plugs are good.

Hi there. My engine is fouling the two lower plugs. Checked reeds seem ok. Optical sensor and new CDI installed. Maybe is the optical sensor in 180 wrong the problem? I wish some one knew something. Thanks guys.
