mixture oil leaks from reservoir thru bottom carburator on 50 hp mercury

[barglow]

I have bayliner boat 2000 with 50 hp outboard mercury motor. Suddenly i noticed mixture oil leak from bottom carburator . It is a gravity leak, meaning if i raise motor it leaks more. I suspect something got stuck & dont shut off oil flow. Please help me diagnose this problem.

Welcome to iboats!

You would be tter served by posting this question in the Mercury & Mariner Outboard section. However, a stuck-open needle valve in one of the carbs can cause this.
