My 17.5 hp Troybuilt pony was not running right. i replaced the usual, spark plug, air filter, fuel filter.... Still no good. I gaped the valves. I noticed that my intake vavle didnt move much. It should move the same amount as the other valve. It didnt. i read up on Briggs made some faulty cam shafts and sure enough my lobe on my intake was rounded. www.smallenginesuppliers.com/ 17.5 HP Briggs & Stratton Intek ohv ic
