Honda HR173 ?

[christer]

Ignition coil for Honda 173. I have used an ignition coil for generators called type 168F. You can find it very cheap at Aliexpress. Some modifications must be done such as the mounting holes must be grinden to fit. I also grinden the metal plates to fit the curvature of the fly wheel better. When grinding on the metal plates hold them together with vice grip or in a vice because they are very soft and are not hold together very well.
