HI, I HAVE A B&S ENGINE 446777 0302 THAT CAME ON A CUB CADET LT 1024 . IT WAS BLOWING ALL OF THE OIL OUT THROUGH THE FILL TUBE I BELIEVE (MOWER IS ACTUALLY A FRIENDS AND HE TOLD ME THAT) ANY WAY IT'S MINE NOW AND I NEED TO FIX IT . IT RUNS GOOD ON ONE CYLINDER NOT SURE WHAT IS WRONG WITH OTHER CYLINDER HAVEN'T REALLY LOOKED . THE MAN AT A REPAIR SHOP OLD HIM THAT HE PUSHED THE PISTON DOWN AND IT WOULDN'T COME BACK UP. I GUESS I'M TRYING TO SEE IF IT NEEDS COMPLETE REBUILD AND IS IT WORTH RBUILDING. I KNOW IT NEEDS A NEW STATOR. FOR ALL I KNOW NOW IT MAY HAVE A BAD PLUG OR THROWN PUSH ROD OR COULD HAVE CRANK ROD BROKEN.IF SO IT ISN'T SOUNDING LIKE IT LIKE I SAID IT RUNS GOOD ON ONE SIDE. DOES ANYONE KNOW WHERE I CAN PURCHASE A MANUAL FOOR REBUILDING IF NECESSARY. PLEASE FILL FREE TO SHARE ANY OPIONS YOU HAVE . GUESS MAIN THING IS FINDING WHERE TO START. THANKS
