not great focus on that pic, hard to see... but yea I reground my valves, trick is not to much pressure and keep pulling the valve out evey few turns to get the paste in the area needed
the fine paste seems good but the course has such big grit in it not sure it can really be effective. I shall give it a bit more next week- are any marks acceptable on seats?
i shall be an expert in abo fire starting by the end of this
