Question
B&S governor
Hi Eric, Boy I hope this question gives you a heck of a challange, because it has me stumped. I'm helping a friend out with his Craftsman pressure washer with a B&S 6.5 hp engine. I cracked it open and found the gov/oil slinger pretty much chewed up AND the camshaft worn down. I couldn't detect anything else wrong. I replace both pieces and reassembled. Compression was good and she started up, except that she was revved way up and on this pressure washer, the engine controls didn't have throttle control; it was basically on or off and the governor maintains the proper rpms. So, I adjusted the governor which didn't help. I disconnected the gov link at the carb so I could manual adj. the throttle. I discovered that there wasn't any kind of action coming from the governor while the engine was running no matter what the throttle setting. I opened her up again and found that the governor had been chewed up. Luckily, it appears that other than some naw marks on the interior casing, none of the pieces got into more sensitive areas, there is some wear on the governor crank arm. So, before I call this, I wanted your opinion on what would cause this in the first place. The unit doesn't have many hours on it and everything else looks good. I'm attaching a pix of the unit as it now stands, and I have more pictures if needed. Thanks in advance. Jeff

Pretty unusual for Briggs to shred governors. Is it possible the governor was mis-adjusted when you assembled the engine causing it to malfunction? I know this has happened to me before.
Are the parts you have re-usable? Make sure the governor wieghts move freely.
How many hours are on the engine? If there is less than 20 hours there may be a more serious problem, possibly a factory defect. Rare,but I have seen a few engines that were not machined correclty.
Let me know if the link helps.
