Honda GC160 DHAF engine

Looking for a honda engine GC160 DHAF 5hp 7/8" horizontal shaft for an excel pressure washer? Old motor has broken intake valve. I have not opened it up yet but figure it's beat. Has anybody seen these survive this?
 
 
After further inspection intake valve shattered going thru the side of the block and made a new hole in the head leaving the engine fubar. I am still looking for an engine does anyone know why the 7/8" horizontal short shaft configuration is so hard to find?
