Hello and thanks for allowing me to register on your forum. Thanks in advance for any and all advice / help.
I am managing a remote ranch in eastern Oregon and I have been bringing an old M274A mule back to life. The engine runs pretty well, last work done was a new carb and new inline fuel filter, did an oil change. Already read here where I should have used an SAE 30 instead of multi grade 10w - 30. Will change that soon. Installed a new pull starter cable last week. This old engine runs exceptionally well except for one issue.
The issue appears to be the crankcase vents allowing far too much oil into the breather / carb. This has happened a couple times where the engine begins to bellow smoke and loses power. I can close the valve near the carb and stop the issue, but this causes pressure to force out oil around the governor. That leak needs to be repaired, but I first need to understand this crank case venting and why it sometimes pushes so much oil into the fuel system.
Thanks if you can help educate me a little more on this engine.
