The 6500rpm rev-limited coil is great for spec-class racing or recreational builds.

Best used with stock flywheels, we recommend using the 138210105 cast aluminum flywheel. Aftermarket flywheels with high-strength neo-magnets may damage the rev-limiting coils if left banging too long on the rev-limiter. 

Coil Air .012-.015″ on stock flywheels.

For reference, the Ignition Timing is set based on the end of the following leg of the coil. 

These Ignition Coils are replacement for 196cc 6.5hp Clone, Honda GX200, Ducar 196, Ducar/Tillotson 212, Tillotson 196R/RS, Tillotson 212R, Ducar/Tillotson 212E, Predator 212, and BSP 196 and 212 Engines.
