Nice work and nice slabs!
How many hours on your Honda gx v-twin?
Many commercial pressure washer guys and mud-motor folks have had issues with electrolysis corrosion on a mini fuse behind the ignition switch at about 100 hours of use. I suspect two dissimilar metals between the fuse slot and the fuse. It gets so bad, your engine won't crank over. BUT, it is usually never that nice denso starter.
Anyhow, pull that fuse and replace once a season. Fill fuse slot with dielectric grease bud!:
