Lead is there to protect the valve seats in 4 stroke engines.
2 strokes don't require lead, so unleaded is fine, probably have to retard
the ignition slightly.

So you think I would be safe using Premium Unleaded (the highest octane

Would I have to drain out my existing tank completly before mixing the
leaded petrol with the Unleaded?

Yes - for that old an engine, you shouldn't have a problem. You might
want to use a good premium 2 stroke oil.

Also sorry to be abrupt but the same thing happened when I did another
post
elsewhere... people started telling me about their old car engines running
fine on Unleaded, I was hoping I would only get boat related answers in
this
newsgroup

Well, some of us have significant experience in that area and it does
relate in a few ways. The question was about additives and that's
some of the answers you received. The fact that the answer related to
Redline was more than appropriate.

TTFN,
