Small Engines (Lawn Mowers, etc.): mac 3516 chain saw, fuel mix, chain lube

Question
I was cutting some wood when a fluid dumped itself out. I know it's not the mixed fuel or bar and chain lube. It still runs but I would like to know what that fluid was. Can you please help me. Thank you for your time.

Answer
 Hello Ian:

 Where did the Liquid Come from on the Chainsaw? A Lot of times if the Fuel Mix is Heavy with Oil the Excess Oil will Leak Out of the Muffler and from Around the Jug Seal. Hope this Helps. Let me know what Happens, Please. I enjoy knowing the Outcome. Thanks.

 Good Luck

 Respectfully

 John
