OT - question about B&S OHV engine

Aug 31, 2009 1 Replies

A B&S 11hp OHV engine followed me home from the dump (it looked so new that I just couldn't not bring it home).



It wouldn't turn over (BAD sign), but there was no sound of a rod flopping around (good sign). I took out the spark plug and oil *poured* out! Took off the carb float bowl & it was full of oil! Looking better



- this is probably minor, operator error, even.



The fuel line goes through this device:

there is also a hose into it from the oil fill tube. This other hose is connected to the oil fill tube well above the normal oil level. There is a separate PCV valve with a hose into the carb, as is usual with B&S engines. So what does this mystery device do? And could it provide a path for oil into the carb?



Thanks, Bob


It's a _fuel pump_. It must use crank case pressure pulses to work a diaphragm. Gentle pressure on the input didn't cause any air out of the fuel ports, so the diaphragm is probably not ruptured. And the mystery of oil in the float bowl is not any closer to being solved .
