Runs great but tappy engine noise especially under load....eases off as you come off throttle.....just valve adjustment ? Any help much appreciated. John. (edited)

Got quality gas in it? Spark plug clean? If the gas isn't old, maybe timing has changed?

When's the last time you changed the oil? Low/old oil gives you some ticky valves
