I recently bought a used 1994, 60 HP, 3 cylinder, oil injected, two stroke. It's been on a stand since I got it. I started to rebuild the carbs today and discovered that the green two stroke oil leaking from motor was coming from the lowest of the three carbs. When I pulled the carbs, I saw it was actually coming from/through the lowest two reed valves behind that carb. I pushed the reed valve open with a screwdriver and the oil gushed out - about 3/4 cup! How in the world did it get in there??? It didn't come through the lowest carb: I opened that up and found no oil inside. The oil appeared to be clean and wasn't diluted by gasoline. This is a typical Mercury oil injection system: oil injected into fuel line before the fuel pump, then sent through the fuel filter to the top carb, then gravity fed to Carbs # 2+3. Hope someone out there recognizes this problem and can tell me what is going on. I'm also hoping for a suggestion or two for correcting the problem.
