I have a 75 HP 4 cycle yami that has carbs. After running the motor for a few hours, fuel will be in my oil. I thought it may be the fuel pump diaphragm so I replaced that. After a test run I found that I have the same problem.
The motor runs great and sounds great, no smoke, no fouled plugs, does not over heat.
I don't know what to check next.
Any ideas ?
