I have a Karcher Power Washer w/ a B&S Vanguard engine. It is like
new, maybe 10 hrs. use. It had been sitting for 6 mo. When I started
it, it was smoking badly, and then shut down. I looked at the air
cleaner and oil was dripping out in large quantity.
There is a vent hose running from the OHV cover to the air filter,
which I discover was the source of the oil.
Any ideas where to go from here?
