Go to Harbor Freight and buy a Chinese Honda knock off for $100.00 and
forget you ever owned the Briggs.

It's on a lawn vacuum, and it was running fine.  My wife was operating it so 
I didn't hear it.  She  said it just stopped, making a bunch of noise in the 
process.   The crack occurred right behind the bearing, inside the crankcase 
at the flywheel end, not the impeller end.

There was a good level on the dipstick and an oil change in the winter so it 
was not oil related.
