29576-55 Magneto Coil Repar Sleeve....
You wont find this in the original parts manuals but quite often the original magneto coil exterior insulation cracks, leaving coil windings exposed.
This repair sleeve is made to slide over the magneto coil windings.
Then heat up repair sleeve gently with torch or lighter.
The repair sleeve shrinks, wraps, and seals the exposed windings!
