Hi, I have a 3.5HP "Vinaro" brand mower with a tecumseh engine (similar to the B&S sprint engine). It's been left in the open without a dipstick and rain/hosing has filled it up with water. The oil is like a light chocolate milk drink. I've flushed it 4 times with engine oil and once with kerosine but it is still discoloured and milky. What should I do to clear the mess up properly? Is it safe to run with any water remaining in the sump. I think any water might bend the rod or damage the engine if I start it with any water remaining but how can I get it all out. Any ideas?
