Just removed this from an engine with noisy worn bearings with a view to saving it for another motor as it looked pretty free of scoring when I took a peek. There are fine scoring marks visible but are they quite passable or should they be rubbed away? Another question is what's the best method to remove the carbon of the crown as I've never done this before and don't want to scratch the aluminium?
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
