I think it is the 3 port. Can you tell from the outside.
I washed dried and reoiled air filter which seems ok.
The bottom end started at factory setting of 2.5 turns from flush but this seemed much to rich. Read another article that says 5 out from closed.
It is currently 3 out from closed. If I richen any further it struggles to pick up at all.

It could be the seals have gone hard over the years then split when you have put fuel through it,
If you take the head off,move the piston down,this will show you the ports,i carnt remember if the exhaust is classed as a port though,but you get the idea
