Not sure if this is the right place but I have a question. After adjusting my engine and getting it working good, why is my white water tank all dirty with oil. Am I leaking oils or something and am I polluting the lake?
Thanks in advance

That is the nature of a 2 stroke engine.-----I say it all the time.----" 2 strokes and oil mixed with the gas is not well understood "

Yes, you are dirtying the lake.

A two stroke needs (roughly) 50:1 mix to run at WOT. At idle about 100:1. So oil not burnt in the combustion process is coming out the exhaust.
