Hey guys i’m new here, i run a small engine repair business and in at a loss with this problem. Customer dropped off a rider with a 15HP Briggs and Stratton that wouldn’t run right (they had tried replacing the carb and bent the choke bar so it was sticking). I fixed the choke lever and got it fired up but it was surging BAD so i tried cleaning the carb with no success, swapped out for a known good carb and still same issue, even tried one off an 18.5 and still surging. I adjusted the governor and that didn’t help, adjusted valve lash and nothing, new fuel filter and fuel line as well as ran it with the gas cap off to make sure there wasn’t any fuel restrictions and once again same issue, replaced with a brand new carb twice as well as new carb gasket and still surging. So at this point my last resort was something broken on the mechanical side of the governor so i pulled the engine off and tore the housing apart and everything looked good, i had a known good governor gear assembly laying around so i slapped that in there and it’s still surging. I’m at a loss now and short of having the customer come pick it up or scraping it im not sure what else to try. What else could i possibly be missing?? Thanks in advance!!
