Fuel in oil

[linemon]

I'm getting what seems to be fuel in my engine oil . Has anyone else experienced this or have any ideas what may be causing it?

Make sure you turn off the fuel petcock when you park it, could be gravity forcing fuel by your fuel float valves into the engine. If you turn the petcock off and still get fuel in oil, then you probably need to work on the carbs, making sure the float needle valves are seating and the float height is set properly.

Thanks for the suggestion mike , I have had a problem in the past with one of my floats sticking, could be that's causing this issue

It's either that, or a hole in the fuel pump diaphragm.

A classic stuck float valve symptom. Can be a bit of grit or munge from corn gas.

I have had the same issue. It was my floats out of adjustment and the needle valves were not completely sealing. Adjusted and cleaned a few times before I was able to get the leaking to stop.

CHANGE THAT OIL!! Gasoline will wash out your bearings and can cause a crankcase explosion! :shock:
