Re: Onan Generator Carbon Knock
Bon Ami was supposedly used in the early to mid 60's on Pontiac motors in dealerships that had some ring seal problems. Add some to the oil....run it for a while and than change it. They might have been using chrome rings.
Was a little before my time but some guys told me about it at a Pontac dealer I worked at in the '70's as a line mechanic....
