I have a 6.5kw 2 cylinder air cooled onan nhd. The manual states not to lap the interference valves (45° seat angle and 44° valve angle)
Is there any harm to lapping them and whats the reason? I noticed older manuals for this same block only suggest avoiding lapping rather than stating flat out not to do it.
