Here's a rewrite of the text: Custom electronic ignition conversion kit for ASP FS400-AR radial engine. Electronic Ignition Conversion Kit Contents: Magnet Ring: Specifically designed to accommodate 3x1.5mm magnets, this ring features a 2mm bolt and nut for secure clamping (CA adhesive also works). A notch is provided for precise timing setup; once confirmed, scratch the prop hub adapter for easier re-timing in case of future adjustments. Sensor Bracket: Requires an 8x10 mm stud, preferably made of aluminum, which needs to be drilled to accept a longer crankcase cover bolt (4x25mm). The stud is then epoxied into the bracket, flush with the bottom, ensuring the bolt pushes the crankcase cover closed without stressing the plastic bracket. Assembly Instructions: 1. Cut the mounting arms off the sensor and align its depth with the magnet ring. 2. Secure the sensor to the bracket using hot glue, making sure the flat side faces the magnets for optimal performance.
