So.........here I was Wednesday afternoon, taking care of grass cutting on the property.
All of a sudden, I hear the little Yanmar stumbling, and powering down.
Shut her down immediately, looked at the fuel gauge, still read 1/4th full. Opened the fuel cap, pushed her back and forth sideways, nope, don't see any fuel sloshing around.
Thought I was going to have to bleed air out of the system to get her back running. Filled up with a fresh 5 gallons, didn't come up to where I normally fill her, just below the filler neck.
Not sure if this engine has an automatic air bleed or not, but the fuel was higher than the engine, so I was hoping gravity and physics would kick in and push the fuel back up to the injectors. Waited 1/2 hour to try, she fired right off.
Maybe I got lucky? Figured I'd share this info anyways, in the event others might run into the same situation.
I'll be making darned sure she's "topped-off" from here on out though.
