I have a 10hp Brigs and stratton motor with a horizontal shaft. It came off a 2002 Billy Goat blower. I replaced it with a honda and just want to get rid of it. It had a problem with blowing push rods and I have replced them 4 times. When they went the last time I replced the engine with a Honda. The push rods are 4 dollars a pieice and are easy to replace. Then the motor will run fine again for a while. Its a problem that briggs and stratton has had with this engine. If anyone is interested PM me or call me at 508-922-6326. Its yours free you just have to pick it up.
