The damper oil sits on top of the mixture adjuster.  There is an O-ring that 
seals the interface between the bore and the adjuster.  After 30 odd years the 
O-ring has turned into graphite and the oil will run out past the needle 
where it mixes with the air/fuel mixture and is burned by the engine.  You will 
never see that amount of oil.

In your rebuild kit there will be the proper O-ring but changing it out is 
tricky.  First you must remove the needle.  This is done by removing the 
indexing screw on the side of the piston.  This is a brass screw and can break if you 
are not careful.  Next adjust the needle to full extension until the needle 
becomes disengaged with the threads on the adjuster.  

Next, using a piece of dowel rod slightly smaller than the bore at the 
bottom, press the adjuster assembly out of the piston.  Take care when you reach the 
end.  There is a clip that holds it in position.  You will be forcing this 
out of the bore and when you reach the end it will fly away if you don't catch 
it.

Once you get the adjuster out you will see the O-ring and the rest is 
obvious.  Assembly is the revers of the above.
