Check the Crank Oils seals also if the Motor has been sitting or a long time since manufactured. Correct Mixture is critical.  Nev

I got given a high hr 582 once and when I filled the rotary valve bottle it ran straight into the crankcase requiring a new crankshaft..seals are part of assembly

No worries.  Mine is oil injected ,I still put 200 ml in every 20 lt for insurance.  With amsoil there is no smoke. Clean exhaust and some people say they even gained rpm with it.

How clean do the spark plugs read? Do you run recommended heat grade, where is your IGN timing set?

My plugs are clean but I use iridium plugs cross reference to the the stock plugs. Would not have a clue about timing.  I haven't touched it. Just clocked over 150 hrs . Runs very smooth . I imagine the timing would still be at factory settings. I wouldn't touch it unless there was a problem.  I like iridium plugs because they supposed to be kinder to CDI box's. I reckon they start better and run smoother with them.

Ignition timing is 15 degrees.

I have the 618 handbook here.

Can't see why you would have to touch it though.
