This is not your fathers Buick!
Its a two stroke.
...Never... ever.... worry about spooge at the end of the pipe on a two stroke.
I would worry if I saw NO oil.
It shows you that you are getting lubrication.
And they always make poppity pop sounds off throttle on decel.
The only thing that is really important is the plug color after a half mile long honk at wide open throttle... Stop on the spot and pull the plug and check the color and report back here.
Then we will know whether you are rich or lean or what.
The only other thing you are talking about here is the idle settings.
And since I am not specifically familiar with your model....
I can just say to keep fiddling with the (2?) idle screws (mixture and speed).
Check where they are by screwing them in all the way while counting eighths or quarters of a turn for a frame of reference.
Keep fiddling till you are happy.
