Reply To: To Hone or Not to Hone

Just spray heavily with brake cleaner through the ports and down between the pistons and walls with the powerhead facing downwards, blow it out with compressed air, then wipe the cylinders with WD40/outboard oil….It’s only fine emery/crocus cloth, isn’t much dust…. Surely not the cleanest/best practice, but it does break the glaze a bit, hopefully bringing a little better ring sealing back to an old engine.
Again, an engine that is disassembled should be hone properly….
