RUST PITS
When rebuilding vintage engines, a person must deal with rusty components. When I have rust pits in the cylinders that do not require sleeving, I treat them with rust dissolver jelly right before honing. It may take a few times to get it and a small stainless brush helps. I believe it stops the rust and oil the spots right after final washing.ÿI’ve had engines on the stand for many days and even weeks without the pits growing or showing rust in my experience anyway.
