Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello, have you checked to see if the oil is overfilled? If it is gas could have gotten into the oil
Was the engine tilted or on its side? Does it smoke when running?
Do you have the engine model number?
Look on the OHV cover
A loose breather could cause that too
It is hard to tell without seeing it.If the breather is tight I'm not sure what to tell you next and will opt out.
